While some traffic wardens can be jobsworths at the best of times I don't think any human just going about their 9-5 deserves that. The man is just doing his job, paying his taxes and trying to put a roof over his family's head/food on the table. I hope they catch the *******s.
Catch them, put them in an overflowing prison system, be out in 1 year? or less.
Nobody cares any more about the justice system, its lost all credibility in the last 20 or so years.
