The sort of rubbish and hysteria you guys are spouting is why terrorist attacks work so well in the US - I don't think anyone at JWN is hysterical over this, but if anyone were, so what? Maybe the hostages or their families are hysterical - is this OK with you?
No one knows if this guy is connected with any group or if he is a lone wolf nutter - does this even matter? He forced two hostages to hold a black flag of jihad to a window - similar to the flag of Jabhat al Nusra. He is also apparantly armed.
However I do wonder about the fact that our PM is at about the lowest level of popularity ever and the budget was released today. Coincidence? - It probably is a coincidence. If not, what are you implying?
