I dont think its 'got tired of them' more like: You have been before the courts on the same or similar charges (or whatever) on two previous occasions, the last time you were warned that (insert what ever penalty was threatened) if you continued to offend. You chose to ignore that warning, so the penaly is applied.
I think persistent offenders of all types need much harsher treatment. I dont see why the law abiding majority should have to put up with a (probably very) small number of offenders who have no respect for the law. If all else fails get them off the streets.
It just feels like a pair of 'people' (insert stronger word) are holding everyone to ransom, because if Network Rail go in mob handed with police support and the cottage owners end up getting hurt they will then play the victim, even although they are the cause of the problem.
