So basically the sub-human was from Manchester, studying at Salford Uni, family from Libya.
Last few months he suddenly started showing hardline Islamist tendencies, scared his mother enough for her to return to Libya, goes off to Libya himself a few weeks ago and then returns to blow up a bunch of kids and parents. "He was known to the authorities". Really? I imagine there were one or two red flags showing up with this guy.
Not good enough.
