It's a complicated issue. There have been lots of people who have gone to Syria to fight with IS and then return to the UK once they find out the reality of that decision. If they hold a British passport they have to be allowed to return. Ideally, they should be rounded up and incarcerated immediately, but these people are usually respresented pro bono by Human Rights lawyers and other "conecerned parties". It's aminefield with people on both sides thinking they're right. Same old, really...
