Doesn't the act of violating planning laws contradict their "traveling" ways? I've always thought it's a bit of an odd one that. If they're travellers, why would they need building control approval and or planning permission for anything?
They seems to have a habit of parking up caravans and then building bungalows next to them, and toilet blocks and other outbuildings...
I don't really see why we should need to make any special provisions for them - we've got planning laws in place for a reason, if travelers are allowed to buy up cheap green belt farm land and develop on it then so should anyone else - obviously this would be silly as we have green belt land for good reason.
They exist outside of society and tbh.. this isn't a good thing - they don't pay tax, girls are pulled out of school early, women subjected to domestic violence frequently, lower life expectancy and higher infant mortality and crime rates seem to rise where ever they end up. Yet they're still happy to use government services when they feel like it and are happy to ignore planning laws that everyone else has to abide by and attempt to develop on sites they have no permission to develop on.
