My wife was pulled over for erratic driving and speeding. She got out of her van and was asked to take a breathalyzer which she did and blew 0.0. The police were convinced she was messed up on something. She passed the first field sobriety test the hand to nose. Then she attempted the one leg stand and she was in heels. Couldn't do it even after taking her shoes off. She has dissociative Identity Disorder symptoms mimic drunkenness. After trying to perform the one leg stand, the arresting officer without asking, started to search her van, He pulled her purse out of her van, opened it and magically pulled out a portion of a meth pipe. This surely cannot hold up? What could possibly be probable cause?
