You don't have a clue, in short. You post your rose tinted glasses stories, which set out an absolutely angelic 'offender' who did EVERYTHING right and just got screwed by the system.
Poor little motorist, does not comply with terms of insurance, gets cancelled, never got any of the (no doubt numerous) letters that would have been sent, there is some kind of an 'oversight' but the only real crime he committed was driving without displaying a tax disc.
Everyone is entitled to do what they want as long as they do it in good faith. The Police are just a bunch of law enforcing scum who have no idea how to employ discretion. Right?
You seem to think that discretion should be employed EVERYWHERE. Illegal tyres, no insurance, anything else you want to add to that list? Discretion is circumstance, officer and offender based.
Had your 'friend' not been tugged he would have driven without insurance indefinitely it would seem, on the basis that he THOUGHT he was insured. Would you be defending him with the same old "Poor chap, did not know" sob story if he found out he was uninsured after an accident?
Posts about 'friends' speeding like idiots, stories about corrupt officers who let off speeding for labour work (Which you seem to appreciate). Then again, who knows what to believe. You are recounting a story as told by someone else.
