I think everyone suffers from "a visit" every now and again. It's not coincidence that trouble comes with them, they are the most dodgy, untrustworthy, trouble making people going.
When they were last in my area, burglary jumped through the roof, as did car thefts, theft of alloy wheels, two of them stole a car and were speeding along the top of my road and didn't notice the T junction at the end and drove through a wall into a house.
Also heard about their scams (selling laptops etc and switching for a laptop bag full of milk etc).
It culminated in them getting on the wrong side of some of the local drug dealers. They got in an altercation and stabbed one of the dealers. Two days later, two travellers were stabbed and one died.
Shortly after they moved on, leaving a mess as usual. They haven't been back since to my knowledge.
I dont feel bad about it, they come and commit crime and are a general nuisance. They are hated by the general population and thus they dont care about causing trouble, or the people they victimise.
The police can do nothing as their hands are tied by red tape. Unless they are caught in the act that is. They know every loophole and know what their rights are and thus pretty much get away with murder.
People are unlikely to get into confrontations with them as they have nothing to lose and thus fight very aggressively.
Sorry if this sounds negative, but I cannot post anything positive about a group of people who have caused nothing but trouble over my 25 years when they "visit" my area.
