My brother (15 yrs old) was recently pulled over and the car was searched. They found marijuana in his friend's purse, but it was not his and they found 3 grams in his pocket that was inside a pill bottle. At first, they charged him with all of the marijuana because he was driving, even though it was in his friend's purse. They ended up dropping these charges because they found 2 counterfeit $100 bills in his wallet. He stated that he found these at school and did not know they were fake. How would we go about proving that he did not know these bills were fake and what would be the process we would have to go through? What could be his possible punishment? Would it be worth fighting? Thanks for your help.
