A bunch of travellers / Gypsies has invaded a local car park and so people are asking what can be done to get them moved on. The answer: not very much. Even though the law is being broken the council and police will not get involved until or unless the landowner (YMCA) gets a Court Order. If that Court Order is ignored the landowner can then (try to) employ bailiffs to have the miscreants removed. If that does not work.....? It is almost as though the landowner is to blame!
The police will only get involved as a last resort - if there is "trouble".
Those of us who pay our taxes, pay the police precept and abide by the rules get no protection. Those who do not give a stuff and constantly break the law get off scot-free. What a way to run a country!
