Well, we really have to agree with Andrea on this. A good cop with draw his gun, go down on one knee, roll over really fast until he is at least five feet from where he started, rise quickly to a standing position and shoot the knife from the terrorist's hand while hitting just the knife and missing the hand. It would be best if he fanned his hand gun enough for just one shot which SHOULD do the job.
We CAN get more good cops if we just have better or good training.
We all know this. Just ask anyone.
