How many times, though, have you jokingly said to a close friend that you should blow X up to solve the world's problems? It's akin to saying we should ship all of X type of people to some third world country. It doesn't mean you want to act on the thing. It might be a joke in bad taste, but words do not equal action. This guy apparently felt "pressured" by this agent to go through with an act. I don't know what that means, but it surely casts doubt on the ethics of the investigating agency.
