"We’ve got big guns, and we like to shoot people. It was rubbish when the government made peace with the IRA, because afterwards we got into trouble if we shot suspicious-looking chaps.
"But thanks to Tony Blair and his War on Terror, we can now shoot suspicious-looking chaps all over again. We just have to bear in mind that ‘suspicious’ now means Muslim-looking rather than Irish-looking."
The BBC has this quote on the same incident: "One of [the policemen] was carrying a black handgun – it looked like an automatic – they pushed [the suspect] to the floor, bundled on top of him and unloaded five shots into him". If true, that doesn’t sound entirely like reasonable force.
Oh, and obviously the police ought to shoot people if they reasonably believe that the alternative is that they’ll blow themselves up. I hope that when the facts of this case become clearer, they’ll show that this is what happened.
Update: sadly, no.
