Upon hearing that there are 500+ English muslims fighting in Syria and Iraq as part of the Isis army I immediately looked online for what would happen to them if they tried to return to the UK. I've listened to the news for days and read the papers, government websites etc. and it seems that they will simply be allowed back in. I find this extremely frightening. Why isn't there a clear line on what will happen to them if they try to return? Why isn't the government being clear that they will have passports cancelled and be exiled?
