Britain debating whether to allow ISIS fighters to return or kill them in Syria

Telegraph:

British Isil fighters should be killed in Syria rather than be allowed to return to UK, a Government minister has said. Rory Stewart said converts who leave Britain to fight for the terror group are guilty of horrific acts and the only way of dealing with them is to kill them "in almost every case".

His remarks come just days after the independent reviewer of terrorism legislation Max Hill QC said young people who travelled to Syria after being "brainwashed" should be allowed to come home and rejoin society.

Mr Hill told the BBC that it was not worth losing a generation of young people who "naively" went to join Isil before attempting to come back to the UK.

Asked by BBC Radio 5 Live's John Pienaar if they had "brought on themselves what they are about to get?", he said: "These are people who have essentially moved away from any kind of allegiance towards the British Government.

"They are absolutely dedicated, as members of the Islamic State, towards the creation of a caliphate, they believe in an extremely hateful doctrine which involves killing themselves, killing others and trying to use violence and brutality to create an eighth century, or seventh century, state.

"So I'm afraid we have to be serious about the fact these people are a serious danger to us, and unfortunately the only way of dealing with them will be, in almost every case, to kill them."

Half of the ISIS fighters from Britain have already returned so there is that problem.  I think it would be wise to send them to someplace like Gitmo where they can be interrogated to discover what plots are afoot.  They can then decide what to do with them based on teh value of their cooperation.
