Laws are just sad attempts to stop regularly occurring problems in society but they don't fix the problems.
If a man in a village gets a gun and shoots a person this could be considered a terrible crime so law enforcements remove the individual. Another man was then shot in the same village by a different person. And this problem keeps reoccurring over and over again, but people still keep getting shot. Why, the cops have removed the people that did the shooting, why is there still a possibility that people could be shot? It's because they haven't removed the problem. The real problem could be the gun. This could apply to many other laws if you just think about it. Identify the problem, the true problems.
