they rock up in towns/car parks and cause havoc, because they are no more than criminals with no respect for anyone else. They just hide it behind a facade of "lifestyle" and "ethnicity".
The big problem with tackling the traveller issue, and we've seen it already in this thread, is that when people hear the word "traveller" then one of two images comes to mind.
1: They think of the ye olde Romani travellers going about peacefully in horse drawn carts, living off the land, bothering nobody and clearing up after themselves.
2: They think of the "modern" travellers who are essentially Chavs rocking around in caravans/transits, breaking into public/private property, defecating all over the place, committing as much damage/crime as they can before having to move on then doing it all again.
The problem is, even though 99% of travellers fall into category two, if anyone ever says a bad word about them (or god forbid recommends new laws to finally deal with them) there will always be people who oppose it simply because they like the category one travellers and that's what they think of when somebody mentions the word.
