No SASE policy hinders prisoner education

I am writing to inform you that this unit no longer allows us to mail out SASE so that people like you can mail information back in that we request. I don't know if this is being done system wide or just this unit. But I do believe that this move is being made to hinder prisoners being able to get outside help because they know that most people will only send us information to help us legally fight back if we send a SASE. No SASE, no information...because most people can't pay to send every prisoner what they request. They don't want us to be educated to resist by using that mighty ink pen and paper. I just wanted to let you all know what was going on in case you start getting more requests but no stamped envelopes to help with postage.
