This is a bit racialist IMO, the high crime rate occurs because those "coloured people" as you call them, can’t get well paid jobs or even any job a lot of the times, and you wonder why a certain proportion of them have turned to criminal behaviour?
Nonetheless there is still, now we are out of the EU, a queue of people coming over across the Channel wanting to enjoy the life that we have so carefully built for ourselves, blimey even the Irish, Scots and Welsh leave their country to enjoy a better life here!
