Yes, they stormed the Café. But two are reported dead (1 the terrorist) and maybe 5 went to hospital injured. Info is not totally sure at the moment.
The terrorist is said to be a lone wolf, an immigrant Iranian, with a long criminal history and was currently out on bail. His Ex lawyer, is also trying to paint him as mentally imbalanced.
There is a pattern. People leave the Islamic countries, or I should say often flee them, seeking a better life. But once in the new country which is not of their culture, they become isolated and disaffected. Eventually they get a case of the F*** Its and decide, for lack of anything better to do, go out with a bang and become a heroic martyr and infamous villain (depending on your point of view).
But really they are just losers who can't stand losing while others succeed. But rather then just take their ball and go home, they blow up the playing field and everyone on it. For all practical purposes insane pawns to be played.
