For those of you who watched 'Making A Murderer' a few months ago what would you ask Steven Avery's lawyers? I am going to the Conversation on Justice event soon that features Avery's lawyers, Dean Strang and Jerry Buting. They are going to do a talk and then have a Q & A at the end. If you were to ask them anything, what would you ask?
