I have no doubt that the FBI told then they had a bomb to sell him, cheap. I have always said that any police agency that provides any contraband to a suspected criminal in order to arrest him in the act of receiving it, they have created the crime and enticed the person into the act.
When I was a site supervisor, I once had a manager that told me to plant some company property on an employee he didn't like in order to send police after him for theft. I quit the next day and immediately hired on with the competition. That would have been illegal and unethical for me to do but it's OK for the police to do effectively the same thing?
A few months later I got that employee hired at the new company I went to work for and he excelled.
