The fact's that the assassination of a significant political figure is essentially a suicide mission. The term assassin is derived from the Islamic cult of the Assassins. A group whose members were induced into performing suicide missions through the use of hashish. Even though more than sufficient grounds have been provided for a seizure of the Federal Government by force it won't happen because those who can do so understand that a false president isn't the cause of the problem. He or she's merely the symptom. The actual problem is the subculture holds the rights of individuals in contempt and is willing to use force to reach their goals. A single assassination won't solve this problem. Though there's no shortage of trained individuals who're able to carry out the mission it won't happen because those who have the necessary skills understand that it'd be futile.
Let's examine the JFK assassination.
The M38 Carcano rifle was
the worst weapon available. Italy was the poorest nation in Europe.
The Carcano rifle used a rounded round. Even the Russians used a spitzer
round. When NATO converted to the 7.62 x 51 cartridge Italy sent the
Garand rifles that were given to them by the American government to a
local firm to be converted to BM-59 rifles. No one who knew Oswald's
background would've hired him for a normal job. The assassin would've been permanently disposed of. A
realistic conclusion would be that Oswald was a very fortunate shooter.
