"Very easy to be wise after the event. If he hadn't run, he wouldn't have been shot. If he hadn't been an illegal immigrant, he wouldn't have run."

For the last damned time: - HE DIDN'T RUN AND HE WAS NOT AN ILLEGAL IMMIGRANT. Neither was he wearing an unseasonably bulky jacket nor did he jump a barrier.

He walked down to the platform in his normal way, picking up a free newspaper on the way. He boarded the train and sat down. - whereupon he was dragged out of his seat, overpowered and, WHILE ABOUT THREE POLICEMEN WERE SITTING ON HIM, shot several times at point blank range.

One question. What happens when the terorists start using triggers that set the bomb off when they let go of them? fat lot of good shooting them will be then.
