lol at this thread, the cop was only doing his job ffs, the plates were moody by the op's own admission, and he'd probably been running them for a while. couple that up with coming off a ban, why run dodgy plates its only giving the cops a reason to pull you over.
as for the excuse "i was just going to change them" i'm sure the cops hear that all the time, 9 times out of 10 it will be bullshit.
the fact is a lot of people break the law with things like speeding, illegal mods and so on. its a choice you make, no one forces you to do it, so dont get pissed when the police actually do their job.
