They won't ever do that. With inmates, it's all about me, me, me. They're the ones who get money sent from their family members to be placed in their accounts. They can order items from catalogs, as long as they are department approved. And they can get packages containing food, magazines, and other allowed items, sent to them each month, or a family member can bring a package when they come to visit. When I was still working, they were allowed 3 packages a month, not to exceed 50 lbs. in total weight for the month. I'm assuming it's changed since then. Gotta' keep the cons happy!!
From what I know about prisoners, and my knowledge has been on the military side, a lot of them are not real savvy in the ways of the world. But one of the consistent displays of prisoners, is the deep feeling that they have failed their families in many cases and make efforts to help them. Will they give to UNICEF? I sincerely doubt it, unless they start making enough money in the joint to need tax write offs.
