I do struggle with this, and what I am about to write could cause offense, but it is absolutely not meant to.
I don't know if there is a distinction between gypsies and pikeys (indeed the term could be the Roma N-word, like I say I am not looking to offend). I live in a fairly small town and we quite regularly see incursions of pikeys. They recently broke into ground near an electrical substation and parked up their caravans and refused to move until legally evicted. When they departed, it was to break into another area nearby where the whole sorry saga was repeated. At each site, when they left they left behind loads of rubbish for others to clean up after them, and had also left human shit crapped out in the open. Presumably this was some kind of 'fuck you' as I am sure their caravans will have toilets.
I have no idea if crime in the region went up while they were in the area. Local social media would suggest it but that is hardly a reliable source. Likewise I am sure there is a chicken and egg scenario at play where they know nobody wants them camping up so the 'fuck you' mentality would be easy to foster.
My point is, they don't do themselves any favours with the rest of the populace. I have really ummed and ahhed before posting this and am still not sure it is sensible.
