JAIL isn't helping

In class, we watched an episode of 30 Days with Morgan Spurlock and how he experienced these days in jail.  From watching his experience, the prisoners that he would talk with more than half were in jail because of a drug related crime. A guy named Travis was in jail because he was addiceted to cocaine, heroin, and marajuana. He had goals for himself, like getting a job when he would get released. And once he was released, he ended up committing two other crimes about 2 months later from his release date. From him being in jail for a long period of time, then already 2 months later he's committing crimes again shows that jail isn't helping these prisoners. What they really need is counseling and other programs that would       support them by becoming drug free. To come clean, and not go back to prison because apparently jail isn't helping.
