No, not feasable. And also... why? Why a big effort not to completely stop him?
I remember on this forum when a policeman tried to stop a shoplifter, who had been banned from the store already but went back to steal, and was caught in her door where she was driving away, dragging him off to a certain death. He shot and killed her and one frreeper wondered why he just didn’t do a warning shot in the air!!!!!
I mean, whuuuuutttt????????
