An absolute superb decision made by the very people whom are privy to security/intelligence service information along with lessons learnt from previous incidences.
“Takfiri” strategy was used for the Madrid bombing that caused so many deaths and appalling injuries.
“Takfiri” strategy was used to kill and maim all those children in Manchester.
"Takfiri" strategy was used for the Bataclan massacre.
Shamima Begum came from a Jihadist state that taught operatives bomb making skills, counter surveillance techniques, insertion methods, and “Takfiri” instruction. Guess who shows up in full out “Takfiri” mode?......Yep! Shamima Begum herself i.e. one minute a remorseless atrocity supporting Islamic "Hisba operative" and next up (you cannot make it up) Western "Takfiri" poster girl.
She is not worth the risk of one child’s life or limb, because whatever she will say can never be trusted e.g. just one example of an ISIS operative like this one whom portrayed himself to be no threat hence his release. Good riddance to her and Jihadi Jack!
