And like I said there, this looks like one of those things that just happens.
Innocent guy gets caught up in the middle of a high-pressure anti-terrorist investigation. Inadvertently raises a few extra red flags by his choice of clothing and by vaguely fitting a description or two. Goes to work as normal, followed by police and military anti-terrorist folks (who, it is worth noting, do not immediately execute him). Heads for tube station, presumably causing another few red flags to go up to the point where they decide to stop him.
In an entirely understandable reaction given his circumstances, he legs it, heading by instinct towards his intended destination. Seeing their suspected terrorist running after being challenged, towards al-qaeda’s number one target over the last few weeks, causes the authorities to switch into ‘stop the clock’ mode rather than ‘apprehend suspect’ mode and the poor sod is dead.
And regarding the 5 shots, I would point out that once the decision is made to kill somebody to prevent them setting off a bomb or shooting someone or whatever, the goal is to make them as thoroughly dead as possible, as fast as possible. Being dead once or five times won’t make any difference to Jean, but if he had some sort of trigger it might have made all the difference to the people around him. And from what eyewitness accounts I’ve seen, this wasn’t exactly an execution - everyone concerned was running flat out and the first instant the poor guy was stationary enough to take a shot at, he was dead.
So, while it’s all very tragic and so on and so forth, how exactly should it have been done? There are people wandering around with a demonstrated intent to kill themselves and as many other people as possible, and access to explosives. The authorities are, presumably, stretched to the limit watching as many suspects as possible. As a consequence, nobody is at all surprised if lethal mistakes get made.
Except you, apparently, who are determined that the “Stop!, or I’ll shout Stop! again” school of policing should be maintained. If it turns out the cops made some sort of egregious fuckup, then fair enough, give them a roasting. But shooting a terrorist suspect because he failed to stop when challenged, jumped a ticket barrier and ran onto a tube train is, in current circumstances, an understandable errror - it’s not like they’re randomly capping anyone who catches their eye. It’s also not standard police procedure, but anti-terrorism is a paramilitary operation, and until the current operational cells are confirmed to be closed down, things are likely to remain a bit twitchy. In fact, it’s just as much fun as when our friends in the IRA were blowing us up in the nineties. Plus ca change, and all that…
