The only place more dangerous to live in than prison is the world outside of it. A quick look at the evening news will convince any viewer that the world is a dangerous place to live. One violent crime is followed by another, and it becomes apparent that human nature has some serious flaws in it. Of course, not everybody feels the need to physically harm another person, but there are too many people who not only feel the compulsion but embrace it willingly. Because the outside world is dangerous, criminal justice becomes vitally important to a healthy society. Prisons are designed to house criminals, and some prisons are designed specifically for the world’s most dangerous criminals. These are the criminals who pose the greatest threat to society.
