The real problem is that our legal system is fucked up and protects those that are a menace to society as much if not more than those that are law abiding productive and contributing members of society. Why the fuck we let rapists, murderers, and other wastes of breathable air out of jail or continue to live is a moral argument that our society is afraid to face or the liberals will argue until they are the next victim. We can eliminate many of the repeat offenders in this world, we just choose not to for one reason or another. With that we accept what happens. But I'm off topic.
