“What Is Prisoner Support” is a zine consisting of writing by current political prisoners on their thoughts on what prisoner support and solidarity means. Compiled for the No More Locked Doors Conference in 2015, this zine offers a number of different perspectives on the importance and necessity of prisoner support. It is especially strong in terms of hearing from prisoners on what support has meant to them during their incarceration. It’s also useful for understanding what types of support are most important and identifying areas where support may be lacking. Contributors range from MOVE prisoners to recently (2015) arrested anarchists such as Eric King.
