but you DO believe that Roy DeMeo killed "200" people...

I'm with Jvanley on this one.
The exact number of DeMeo crew victims will never be known but the FBI estimate it to be between 75-200.
200 is maybe a slight over reaction though.

THe thing that makes ME believe the rumours about DeMeo is that DeMeo never talked himself - everything that is known about him comes from third parties (Dom Montiglio, Vito Arena and Freddie Dinome).
Crimes alledged to be the handiwork of Roy and his gang have been verified.
Most of Kuklinski's claims have not.
Some smell so bad that the bullshit is obvious.
Like when Kuklinski claimed he killed Jimmy Hoffa in Michigan and then drove all the way back to New Jersey with him in the trunk!!!!
Michigan has plenty of lakes and woodland - who in their right mind would drive half-way across the USA with a body in their trunk and risk a highway patrolman pulling them over?

I'll believe DeMeo rumours over Kuklinksi rumours anyday
