Americans are vulnerable and can be easily murdered or injured, if they don't learn invisibility technology. Because these invisible personnel can induce their targets to have cerebral hemorrhage, heart-attack, cardiac arrest, symptoms of Alzheimer's disease, and symptoms of Parkinson disease, etc. over several decades with different weapon and illness/death inducing techniques.

What is invisibility technology? According to inside information from former
Taiwan President Chiang Kai-Shek, the invisibility technology of Philadelphia
Experiment has been developed successfully to use on human after WWII by
US Navy. After using invisibility technology on the personnel and their
equipment, they will become invisible, tiny and can levitate.  The tiny invisible personnel and weapon are unsuitable for military use, it has been transferred
for use in surveillance system. In 1950s, this invisibility technology was
transferred to Taiwan's surveillance system. Based on the levitated ability
of invisibility technology and wearing a propulsion device on back, every
invisible personnel can move as a flying ant (equipped with weapons & mind
machine). Thus, the invisible personnel can gently fly onto a victim's head
to read one's mind and mind control him without the victim's knowledge. Also, they can gently land on a target's body (near any organ) to induce illness/death without most victims' knowledge (But so far, they still cannot explain why
humans become tiny in the electromagnetic field).

The unlawful life control surveillance system's establishment is based on
atheism, materialism & communism. Why? I would use Taiwan as an example to
explain it in details. Chiang Ching-Kuo was the head of Taiwan intelligence
agencies and internal security in 1950s. As a former communist (during his days in Soviet Unions), Chiang Ching-Kuo still clung on to its'
atheistic and materialistic beliefs. It means he believed that human is purely
composed of materials without soul and God doesn't exist. So, the concept of
reward and punishment after death for one's deeds in the life would not be a
factor in his decision.  His communistic and atheistic belief caused him to
regard people's lives as properties and in the communist ideology, the
properties do not belong to individuals and can be distributed.  Thus, when
pursuing invisible personnel's unlawful interest, these invisible personnel
would toy with anyone's health and kill anyone. As an atheist with considerable
power, Chiang Ching-Kuo would not have any problem about doing something 
bad if he felt he could get away with it in life. So, he used invisible personnel
in conjunction with psychotronic weapons and illness/death inducing techniques
to create an unlawful life control surveillance system in Taiwan in the 1950s.

Also, Chiang ching-Kuo believed that the people need to spy on each other
(like in communist society) to secure everything and avoid unlawful life
control from being exposed.  Thus, his invisible operatives also recruited
operatives and collaborators from every walk of life (e.g. Banking system,
hospital system, Justice/court system, education system, transportation
system, business, finance & insurance system, food market, hotel/restaurants,
all religions, many different media, psychics, psychiatric institutions,
etc.) in order to mind/life control anyone.

Chiang Ching-Kuo kept the secret of unlawful life control and invisibility
technology from all other public officials (including the President Chiang
Kai-Shek, etc.).  The only other people on Taiwan who knew of it were the
invisible personnel themselves and those officials directly involved with
them.  President Chiang Kai-Shek only became aware of invisibility technology
because of a loyal intelligence agent who secretly notified him of it after
the invisible personnel injured his knee (see details on Part II-A of my
website).  When pursuing the invisible personnel's unlawful interests, they
would betray their country (see staged car accident case on
http://members.aol.com/alanyu5/part3a1.htm ) and would betray their blood
relatives (e.g. Chiang Kai-Shek was injured by the invisible operatives of
Chiang Ching-Kuo).

Since the unlawful life control surveillance system in Taiwan was
secretive and evil, it would most likely also be secretive and evil in US
and other countries because these invisible personnel is a secret
international group and there is no national border between them (see
http://members.aol.com/alanyu5/part3a1.htm ).

The use of invisibility technology in USA has been proven in many incidents and evidences (see details on http://members.aol.com/alanyu5/part1b1.htm ).

The CIA death inducing research (induced heart-attack, or cancer) in 1950s and Defense Advanced Projects Research Agency's classified research of operation Pandora from 1965-70 are two solid evidences to prove that illness/death inducing techniques have been secretly developed.

(Source) "Assassination by 'Natural Causes' - CIA Considered Inducing Death", WASHINGTON POST, 4/2/79
==========
Heavily censored CIA documents from a quarter-century ago (1950s) show the Agency considered performing experiment on terminal cancer patients under the guise of "legitimate medical work. The CIA project apparently started with an undated, unsigned note indicating concern about the vulnerability of US leaders to assassination by "natural causes." Knock off key people," the heavily censored document said, "how knock off key guys ... natural cause... Human subjects would be available for work that could be carried out as legitimate medical research..."
==========

First, let's see who have chance to create heart-attack on a victim? Obviously, only a surgeon in operation room has chance to stop blood flow into a patient's heart to cause it, or the invisible personnel use the radio-frequency weapon to cause it. However, to induce heart-attack on a patient in the hospital's operation room without others' knowledge, even a surgeon cannot do it. That's because several medical staff are always in an operation room. Also, when the involved LEO, police of surveillance station/system want to induce heart-attack on a target, it means they want to kill him immediately- no matter the target is at home/workplace car, boat, plane, etc. Thus, only invisible personnel are available to become such kind of reliable assassin/murderer.

Second, before the CIA death inducing research project (including heart-attack & cancer) stared, there was an insider of the project had used an unsigned note to indicate his concern about the vulnerability of US leaders to assassination by "natural causes." Why?

Because such death inducing method is not as usual to train a professional gun man to kill a target with gun. The originally traditional method will obviously be known as a homicidal case and the murder suspect will be openly searched.

However, the new death inducing methods will be secretly used by the invisible personnel (who other cannot see) with psy (nonlethal) weapons which is silent and leaves no signs of external injury on victim's body. Thus, their victims' deaths will always appear as the result of natural causes. Why can these homicide victims be mistakenly believed to have died of natural causes? It happened because following three reasons: (a). The tiny invisible personnel's murders always leave no evidence of an intruder: Because tiny invisible personnel can secretly enter a target's home/office, vehicle, etc. through electric system (or s small hole) then leave no evidence of an intruder. (b). The tiny invisible personnel's murders always leave no signs of external injury on a victim's body: Because the Psy (e.g. radio-frequency weapon, infrasound) weapons can be used to kill a target and leave no external signs of injury on victim's body. (c). The invisible personnel's murders always leave no evidence of a struggle: Since unknowing target will not know his pain is caused by invisible personnel's attack, he will not resist and leave no evidence of a struggle. Based on above three reasons, a coroner unaware of these technologies would only conclude that the victim died of natural causes, even though the cause of death is obvious inconsistent with the victim's overall health. For example, Senator Paul Coverdell was murdered with cerebral hemorrhage inducing technique although he had no warning signs of stroke (see details on Part II-C3). Also, Mr. Carlos Ghigliotti, a healthy 41 years old expert witness of Waco lawsuit was murdered with heart-attack technique although he had no heart problem before (see details on Part II-C4 of my website).

The above CIA classified death research proves that since late of 1950s, invisible personnel of surveillance station/system can induce their victims to have heart-attack over several decades. Also, from 1965-1970, Defense Advanced Projects Research Agency (DARPA) had another project of operation PANDORA to study techniques on how to induce cerebral hemorrhage (create leak on blood/brain barrier) and induce heart seizures (inducing heart dysfunction and cardiac arrest) in US (see details on source).

(Source) "Some Aspects of Anti-Personnel Electromagnetic Weapons" by David G. Guyatt, Prepared for the 1996 International Red Cross Symposium: The Medical Profession and the Effects of Weapons (3/8/96)
==========
From 1965 through to 1970, Defense Advanced Projects Research Agency (DARPA), with up to 70-80% funding provided by the military, set in motion operation PANDORA to study the health and psychological effects of low intensity microwaves." This project appears to have been quite extensive and included (under U.S. Navy funding) studies demonstrating how to induce heart seizures, create leaks in the blood/brain barrier and production of auditory hallucinations.
==========

So, the induced cardiac arrest and cerebral hemorrhage techniques also have been developed over several decades. Thus, these invisible personnel must have induced many victims to have heart-attack, cardiac arrest or cerebral hemorrhage (see details cases on Part II-C2, C3, C4, C6 and Part V-B1, B2 of my website).

Why would I investigate these cases that Americans suddenly sufferred cerebral hemorrhage, heart attack. carfdiac arrest to die ?  Well, I would like to exp[lain it
in details.
The CIA's induced heart attack research (since 1950s) had passed half century
and must had been used to induce their victims to have heart attack (see details
on http://members.aol.com/alanyu5/part5b1.htm ,
http://members.aol.com/alanyu5/part2c4.htm ).  The classified research of operation Pandora proves that since late of 1960s, the invisible personnel must have induced many victims to have cerebral hemorrhage (see http://members.aol.com/alanyu5/part2c3.htm , and http://members.aol.com/alanyu5/part2c6.htm  ) or cardiac arrest over several decades (see details on http://members.aol.com/alanyu5/part2c2.htm )
However, so far, all victims who suddenly died of heart attack, cardiac arrest or cerebral hemorrhage will be ultimately ruled as the result of natural causes.  However, their records prove that none of these victims' cases (who suddenly
died of cerebral hemorrhage, heart-attack & cardiac arrest) had ever been 
recorded on medical literature as a homicide case. It means these victims' sudden deaths in past several decades have all been decided as the result of natural causes.  However, it is an obvious lie.   Because there must be some victims who had been murdered with heart-attack, cardiac arrest, or cerebral hemorrhage
inducing techniques in past several decades.  Their rulings only proves that
the medical examiners either have no knowledge on invisibility technology
(and induced illness/death techniques), or intentionally help to cover-up
their crimes of murders because they are associated with involved police and
agents.  Obviously, many involved physicians have taken part in the above two
classified researches. But they neither mentioned these illness/death
inducing techniques to the public, nor admit invisibility technology existing.
These facts prove that there are many cooperated physicians (who associated
with involved agents and police who use invisibility technology) have involved
to mislead the public.  Taiwan's examples prove that hospitals' physicians
had secretly cooperated with the involved police and agents (who use
invisibility technology) to mislead their targets.  In US, Microwave
Harassment & Mind Control Experimentation (by Julianne McKinney Dec/1992)
had also reported that cooperative physicians had involved in many reported
cases to mislead or mind control their targets.

Examining the rulings on these victims' sudden illnesses/deaths with the induced illness/death techniques, they either didn't tell the truth or didn't know the truth.  Since they  either do not know the truth, or do not tell the truth, the involved police, agents and medical examiners do not qualify and do not have credibility to rule that if a victim's sudden suffering cerebral hemorrhage, heart attack or cardiac arrest is the result of natural causes, or from a attack. We certainly cannot trust their investigation anymore.
Because based on their records in past several decades, they will also claim
and decide that all victims's deaths (who suddenly suffer cerebral hemorrhage,
heart attack and cardiac arrest to die) were still only the result of natural
causes.  This also prove that involved agents, police and their operatives
(invisible personnel) can easily use their law enforcement's identities and
influences on associated institutions to cover-up the invisible personnel's
crimes of murders.

So, we cannot trust the judgment of these nonlethal weapon users (involved police & agents) anymore. Actually, these nonlethal weapon users (police & involved agents) must recuse themselves from investigating these kinds cases (which the victims died of sudden heart-attack, cardiac arrest, cerebral hemorrhage, etc.). Because these users can induce victims to have sudden heart-attack, cardiac arrest and cerebral hemorrhage with their psy weapon & invisibility technology. Unfortunately, so far, they never recuse themselves from investigating such kinds of cases. So, if the decease is a victims who had been murdered by invisible personnel with death inducing techniques, these nonlethal weapon users can easily cover up their crimes. Well-informed Americans (on the uses of nonlethal weapons & illness/death inducing techniques) must analyze these cases (which the victims suddenly died of heart-attack, cardiac arrest, or cerebral hemorrhage, etc.) by collecting facts regarding the death (the decease's health history, decease's recent activities, etc.) to determine the true cause of the death (whether or not it was a murder). This analysis would enable us to find the motivation for the murder. Then, analyzing the capabilities nonlethal weapons, illness/death inducing technology with how the victim died, one can determine how the victim was murdered.

The local involved police/agents should also recuse themselves in any case that
a person who heard "microwave voices" then caused murder.  Because local involved police/agents have used mind control technologies (including invisibility technology) and devices (including microwave voices device) for decades.  So, they and their recruited operatives can easily use invisibility technology and microwave voice device to send their microwave voices to any unknowing target.
The microwave voices can be  easily used to drive an unknowing Americans crazy, or drive an unaware, violent person to kill (see details on http://memberes.aol.com.alanyu5/part1a4.htm )..

After several decades' development on illness/death inducing techniques, these invisible personnel (nonlethal weapon users) can induce their targets many different kinds of illnesses and deaths. It means that by using different weapons (infrasound, microwave, chronal gun, radio-frequency, etc.) and illness/death inducing techniques, these invisible personnel can induce the symptoms of Parkinson disease, Alzheimer's disease, diabetes, flu, and kidney, liver, heart dysfunction, impotence, heart-attack, cardiac arrest, cerebral hemorrhage, vision deterioration, cause a victim become blind, losing memory, losing teeth, damage digestive system, damage excretory system, etc. (please see details on Part V-B1, B2, C of my website).

Recently, Mr. Charlton Heston announced that he has symptoms of Alzheimer's disease. According to a news article from New York Times (12/31/95), the patients who have Parkinson disease are three times more likely than normal elderly to develop Alzheimer's disease. If Mr. Charlton Heston never has symptoms of Parkinson disease, his symptoms of Alzheimer's disease could be caused by invisible personnel of surveillance station/system. Because invisible personnel/nonlethal weapon users (involved agents, police & their recruited operatives) dislike pro-gun persons. If they can ban guns in US like Taiwan, UK, they can use invisibility technology to secretly induce illness/death on anyone without fears. So, Mr. Charlton Heston need to learn invisibility technology from me (or my website- see details on Part II-C1) to protect his basic right to life if his symptoms of Alzheimer's disease are caused by invisible personnel with their weapons.
