Unfortunately I fear it’s quixotic mix, the Them have the power to locate you down to an eight foot square just by the signal your mobile emits even when turned off. But they can’t do that to everyone, they don’t have the resorses. Or the willingness to fill in the mind numbing quantities of paperwork required of them. Give em cause and they’ll murder your mother just cos you stood next to a hoody smoking a joint once, but if they think you’re small time or essentially no real threat and you may find you get away with far more than you’d expect. reckon the best policy is to try and remain below the radar but if trouble looms keep your cool and try and reason with em. they can’t all be baton wielding nazis. Can they?
