She is our problem, we should deal with her.
Well, legally speaking, that's simply not the case any more.
Under British law returning jihadis have only been prosecuted for crimes they have committed in the UK.
One that springs immediately to mind is the fella that spent 2 years in ISIL in Syria, got back to the UK under his own steam and got done for his continued financial assistance and firearms offences committed
here. Not the rape and murder of children that we now know was pretty standard fare during his time as "an accountant" there.
He got 8 years and will likely serve 4.
In my opinion that's not justice. It absolves him of everything he was involved in, in Iraq and Syria. IIRC the presiding judge even commented on the fact that he couldn't sentence this piece of shit for other alleged crimes. Two of his mates are now doing life without parole in ADX Florence, for their part in the execution, by public burning-alive, of a young Jordanian pilot. By contrast, you or your children could be sitting next to this bastard the next time you catch a bus into town.
The cases of returning ISIL
brides being prosecuted by their European home nations (that I'm aware of) are in Germany, where one woman got 10 years for aiding and abetting the rape and murder of a 5 year old Yazidi girl. Another got 5 years for her part in ignoring/abetting the systematic rape, and
active participation in the brutal beatings of an ISIS sex slave.
FIVE FUCKING YEARS! .... She’ll likely do 2 or 3.
Forgive me for not sharing your confidence in European justice apropos the ISIS reign of terror across The Caliphate.
To my mind it's hard to imagine a clearer case against repatriating people who've joined an organisation that has sworn to kill your children and raped their way across two sovereign states.
