Why would it be tricky to strip British-born Jihadis of their citizenship?
I just said I don't know the specifics. If you are interested in this topic, why not try google? I mean, it is your countries laws after all right?
In many countries, mine included, removing citizenship for people born citizens of a given country is very difficult, whereas putting them in jail is relatively easy.
I don't want to derail this topic out of respect of the victims so I will bow out of this discussion.
