My view is, the options left to law abiding people are getting few and far between,as an approach some people may find my method disturbing
But the criminal makes the decision to break into the car.
operating outside the law is dangerous, however I would be more than willing to listen to some else's alternative, even if it was 50% as effective.
Anyway I think some one should set up a company selling these things, stabbedarses are us. sounds good.
