This is a good example of a practice where exemplary sentences are needed.
For example, if everyone 'rushing' shops got 5 years inside - no exceptions - I suspect it would not happen very often.
As for the mess they make in playing fields, etc.; this is why we need something like the Spanish Civil Guard. Not easily intimidated and able to be mob-handed and armed if necessary. Bear in mind the mugs - Council Tax payers - usually have to pay for the clear-ups, and it isn't cheap. They should be 'persuaded' to clear up their own shit.
