Making a homicide appear to be a suicide is a common method used by mobsters to dispose of their enemies. This fact is well known among the intelligence and law enforcement community.
A couple of likely examples would include the "suicides" of Madam Debra Palfrey who claimed to have important and incriminating evidence involving high government officials and pertaining to a 9/11 cover up,

and, the "suicide" of Vince Foster:

People with knowledge of ZOG in high places whose credibility is widely accepted, and therefore hard to destroy, may also be considered dangerous by the Zionist elitists and their criminal associates.
Therefore it's up to the obscure masses to get behind the movement to expose their conspiracies. Those close enough to the top to be able to shake things up are in too much personal danger to be able to act. Not only may they be threatened personally, their family members are vulnerable to attack as well.
The so called "Russian" (Jewish) mob is noted for employing this last tactic, something that the old Sicilian mobsters were unlikely or reluctant to do since it ran against their "code of honor". Mobsters steeped in the tradition of Kol Nidre are unlikely to follow any code of conduct except perhaps the one which forbids them from stiffing their own tribe.
