So this coward terrorist bomber got back from Libya within the last week. This seems to be a pretty common trend - travel back to the strongholds, plan/train/etc, then come back and kill people.
Going back to the point made last night (can't remember who it was,) by taking out the strongholds, you remove the ability for these scumbags to go there and plan attacks.
Also, shame on the UK for letting this asshole back in. If you travel to one of these countries, you should stay there as far as I'm concerned.
