The example is maybe a little over the top,this is not happening every day.Is your solution to shot the suspect.Maybe in America where they have Castle Laws,but even there it does not seem to deter much crime,they still have crimes every day.
Career criminals are treated with kid gloves but no government has done much about it,many MP,s are lawyers and laws are made with built in loop holes.The laws would have to be much more simple and punishment much harsher,this has not been accomplished by any governments no matter how big their majority was in the house.
