I think trying Osama is the perfect thing to do. What I can see maybe NOT doing is definitively revealing his background and ineligibility to have ever been president, calling into question every action he took for 8 years. Or things that would taint every case the FBI has been involved in for the last 10 years.
I am sure Trump is not going to let the evil hoax known as 0bola stay in obscurity. PM just sent.
