I wasn't talking about a court of law but in context to conspiracy theories.
The lack of evidence applies everywhere in every type of crime. Those are crime stories as well. The theory is, some people don't think or believe they are committed by those the reports suggest, that's all. It's the owner/owners of the crime that is in suspect not the crime itself. No one would have believed Snowden if he didn't have any evidence to back it up, but the truth is now out there. And you saw the President lying right to your your face just last week.
Anyway, I do agree that not all conspiracies are true. Sometimes people tend to go overboard with it.
