Firstly I think I started an off topic launch with my response, however, thanks 500N, your link made interesting reading.
Problem being I believe UK has let it go to far, for too long and there is no will to do anything by the politicians and the police are hamstrung by them as well, if the law abiding indigenous population of all backgrounds stood up and said enough and tried to rebel they would be jailed.
I heard on the news that there is consideration of possible asbos being given out for those returning from fighting with the IS crowd, what message is that sending out, back on topic maybe they should be taken out by the latest version of napalm before they get a chance to get back, save the expense and hassle.
