I find those activities troubling and I don't think it serves the purpose of ameliorating them to pull international terrorists under the umbrella of police and criminal enforcement. The protections available to ordinary criminal defendants has already become quite eroded and distorted by the necessity of accommodating enforcement against organized crime and drug kingpins within the same framework.
I think you have to be a little careful here, because while the distinction between military action and police action is a good one, the classification of valid responses to terrorism doesn't necessarily follow. Some effective responses to terrorism have been, essentially, police work. And, obviously, some very ineffective responsive responses to terrorism have been military.
