OK...say that he is a wannabe. What if this 50-year old wannabe, decides that he wants the attention of the FBI so badly that he does some terrorist type deed, just to get their attention? (geez...I guess I am learning what it is to be paranoid)
I agree with you, they need to lock him up and throw away the key.
He might do just that. Clearly this guy is trouble. However, I think it's highly probably that this idiot was considered too unstable to be part of an international plot. I think the FBI cleared him of any involvement.
I don't think $1000 bail is high enough. I'd make it $1 million. I don't want him on the street because I think he's likely to do something.
It's difficult to prosecute people for crimes they haven't committed yet. And that's the situation they're apparently faced with now.
