This is the problem with the whole "Mafia/CIA/Castro/,etc. conspiracy theories. The actual evidence of any of these groups being responsible does not exist,and never has existed. Note that I said "evidence". Speculation is another thing.

Here we have a 100 year old woman who just recently decided to "reveal" the truth behind Ruby's death. Falling back on what I can only assume is her comprehensive medical background, this nitwit says the following: "He didn't have cancer," said McCoy. "They poisoned him. Somebody did." Ah,the elusive "somebody". Finally at long last,we've solved the mystery.

The reason that the conspiracy buffs keep selling books and videos is that a significant number of Americans are idiots and do not require any type of evidence. Instead,they move their lips when they read,and eat popcorn in front of the TV when the next "JFK conspiracy" theory goon tells the story of some guy, some place ,who told him some stuff,50 years ago.
