Another point, If I was chased by people with guns, not in uniform, I too would run, regardless of what they shouted at me; I'd be more concerned with getting away. Does this make me a terror suspect?
Many ways exists to detonate bombs which wouldn't requier him to "reach a bomb inside his jacket."
And as for the running, then you might run from a group of armed men claming to be the police in a country where arms are rare in the population, and then run into the subway after the system has been hit by 2 rounds of bombs in a forthnight, where only luck would have it that not more people were killed by fundamentalists.
I'd still claim that it is stupid way to act if you have nothing to hide, and while tragic that one innocent died - I can still easily understand the issue.
Nobody ever said that the western world and its police force has 100% successrate each and every time. I'd still take my chances with "our" policeforce while they try to protect hundreds of innocents.
Mistakes will happen, and they will happen again as long as we are in this state of "war" with terrorist.
