I live about 300 metres from the beach. Nearby is a lovely coastal garden and beauty spot. It's always in very good shape and the neatness and cleanliness is generally upheld. Illegal campers/travellers/gypsies - whatever one cares to call them, set up overnight a couple of summer's ago. Everything changed. I couldn't even walk my dog in the area because of all the broken bottles strewn everywhere.
Perhaps it was malicious locals who ploughed up the lawns with wheel spins, then drove off, framing the travellers. Perhaps it was malicious locals who dumped half a ton of human waste, tatty clothing, dog excrement, even chopped off large parts of magnificent trees. Maybe actors were hired to pretend they were foul-mouthed ragamuffins and delinquent children hell-bent on being anti social. Perhaps it was someone from the council who put the broken glass everywhere.
Nothing should be taken at face value. There could have been some, or even a majority of decent people amongst that travelling community. it's just a shame that a minority who appear to live like pigs spoil it for everyone. If so, maybe the decent majority of travellers should disassociate themselves with the slovenly ones. I have nothing against "travellers" per se. It sounds a rather romantic existence. But Enid Blyton never wrote of the reality about where to take a dump safely and hygienically, illegal occupation of private land, the perils of poorly educated children and the naughtiness of cash-in-hand jobbing.
