Nobody should be put at risk trying to go and get Shamima imo, but if she does manage to make her way back to the U.K. we have a legal responsibility to take her in and deal with her.
I actually feel some empathy for her, despite her beliefs and actions. She willingly went to join a group who openly and proudly commit the most horrific crimes against other human beings, I condemn that of course (and I don’t think fifteen is really young enough for people to say she didn’t know what she was doing, at fifteen I had a very strong sense of my own values and morals that I’ve held well into adulthood, she clearly believed what she did very strongly to go to the lengths she did and I don’t think you can attribute that to her age), but similarly I can still feel empathy for what her life must be like now, having watched her children die and being held in a refugee camp, and I can’t say if I were in her position I wouldn’t be doing anything I could to get back to England.
None of us have a clue whether she genuinely does believe in or condemn IS ideology whatever she says in her interview, she’s not likely to openly condemn them when she’s being held securely in an area full of fled IS supporters, that would be dangerous and foolish in the extreme.
It wouldn’t surprise me at all if she is telling others where she is that she’s going to try and get back here to carry out terrorist acts, either because she is or because she figures once she’s back here she’s safe. I do think she poses a huge danger to us. But as the law stands if she is able to get back to the U.K. we will have to deal with it whether we like it or not.
