What is a legitimate "conspiracy theory"????
An explanation that fits the facts better than the Government's cover-up explanation does -- IOW, one that correctly describes a real conspiratorial act.
Example: the front of Vince Foster's white shirt was almost free of blood. Gunshots that disrupt the brain while the heart is still beating produce copious volumes of blood. (I have observed this phenomenon first-hand.)
Legitimate conspiracy theory: the 38-cal gunshot wound to Foster's brain via the roof of Foster's mouth was administered post mortem -- even though "the official explanation" claims otherwise.
