Right, my bit of right wing for the day, I'm not a Daily Mail reader/believer, there's a chuffing ton of immigrants in this country that we'd be stuffed without, and that includes 20% of the RAF during the Battle of Britain, however, as a very simple rule - if you're not of UK birth, found guilty of a violent crime = deportation. We've simply not enough spare cash/time/resources/Police/admin to waste on this scum. Get rid, let someone else sort them. And in certain countries I'd imagine that a slap on the wrist/ or free bed & board & entertainment & social networking scene (sorry, more commonly known in this country as 'Prison') is not the standard punishment over there for such violent crimes.
All the very, very best to you and I hope you feel 100% as soon as possible, we're all on your side, that's for sure!
