This just like most violent crimes could be avoided and or made much less likely to happen , if the existing laws are strictly enforced with out the bleeding heart morons whining that punishment are to strict. If the punishment for committing a crime is not detouring people from committing a specific crime then the punishment is not adequate. There are way to many laws. Many laws are redundant but if not applied they are meaningless. When people object to a punishment being to severe it usually is because these same people are in fear of receiving this punishment. And rather than not committing these crimes to avoid the punishment they would much prefer to get rid of the punishment.
