This is a well-known problem. We often hear testimony from reoffenders—people who get out of prison, only to return. They say it is very easy for them to get what they want and that a well-established infrastructure exists within our correctional system. They talked about projectiles and all sorts of things. Ways to gain access to a variety of drugs are now very diversified. It even appears that people are making drugs on site using various substances obtained at different times. Ultimately, they are making a cocktail.
How can this be prevented? As I often say, outside gang structures are sometimes reproduced on the inside.
