I don't doubt the victims of any crime suffer enormously from it, but the government's job is to take a proportionate response to that having done a balanced risk analysis, and the fact is that terrorism poses precious little risk to us, and especially so when we're not engaged in overseas wars that encourage retaliatory attacks on our shores.
But we are engaged in overseas wars that do encourage retaliatory attacks on our shores.
We still have boots on the ground fighting Islamic extremists in Afghanistan, Syria, Iraq, Mali and Libya. So the threat is still there, it hasn’t gone away.
Terrorism or rather asymmetric warfare by its very nature can with a relatively small act have a greater effect on an opponent or nation state. So yes there is a limited threat, however even a “small” act of terror can have a big impact overall. By that I mean it has the ability to bring distrust, fear and anger amongst diverse cultural groups within a country that suffers the attack.
The Government is damned if it does and damned if it doesn’t. As an example, if they let these U.K. isis fighters back in and there was a subsequent “related” terror attack in U.K. soil then the govt would get hung out to dry. Likewise if they strip nationalities and deny them entry to the U.K. to contest their cases it is seen as inhuman.
I see it as a case of risk assessment and mitigation. The government are in possession of far more active, relevant intelligence on these matters than either you or I. It is their job to manage the risk as they see fit, as long as it follows the rule of law. In the case if Shemima Begum I feel she is being made a scapegoat and her case is being used as a defining line in the sand.
