There's no need for me to be nervous around cops in England, well unless i was pulled over and i had an O or a QB or something. Then it could get interesting. I think Americans have more rights regarding being searched, coz i was stopped and searched when i had weed on me and i told the cop, i don't consent to a warrentless search. He told me i'd been watching to many american movies... Well they did catch me and my friend smoking a joint so that was probable cause i guess. If i was in america and i had any amount of bud on me, even 0.1, i would keep my mouth shut and answer questions when i feel it would benefit me or not get me in trouble. I think it's a crime to lie to a cop but there's no crime in exercising your right to silence. You have the right not to incriminate yourself, use it!
