But maybe it cause some to read books and that can be only good.
I must defer to your judgement as I know nothing about the prison system, but I add that my optimism about it comes from my own life. After I bought my Kobo reader I started to read books and I was on a much worse road than a book reader before.
As I mentioned in one of my other posts, NY's prison have libraries and law libraries, where they can take out books, read newspapers and magazines. They can also purchase those items on their own through an account, or have someone send one to them, or bring it in a package. A lot of times, the library in the prison that I worked at, got new released books sooner than my local library did.
