My son was attacked by his girlfriends drunk father one night. We are now proceeding with a felony jury trial in January for malicious wounding. My son posted a pix of his injuries on his my space. a friend saw it & asked what he is going to do. My son posted that he is going to sue him for all he has, hOuse, money car, etc. His ex-girlfriend made hard copies and gave them to her fathers lawyer. Can this be used?
