I was about to write a response about how my cell phone isn't a bag. But, then I realized I feel almost as dirty knowing they could go through the bag as I do thinking they might be able to go through my phone. If I've already been arrested for something, why do they need to be in my bag? Clearly they already had what they needed to arrest me in the first place, why poke around for more? (sometimes your posts make me paranoid) *edit: I understand officer safety, but thinking of already being arrested I assume I'm in custody, and effectively neutralized. And, if I never made any motion or gesture towards my bag it seems safe to assume I am not armed or if I am it's not to hurt the police. Maybe I just am not thinking criminal enough ;)
