The witness' account is vivid.
The dead guy may have been about to blow up the Tube. The guy may have been a scared South Asian fare jumper. Only time will tell. We don't know and won't for awhile.
But today's developments pushed me to think about what it might mean here in the US, if, as the BBC explains, "shoot to kill" becomes the norm in trying to stop terrorist bombings.
In the US, as shown in the National Rifle Association map above, all but 4 states allow some carrying of concealed weapons by permitted private citizens. The NRA touts these hidden guns as useful for self-defense.
Perhaps -- but how long will it be, if US police adopt the "shoot to kill the terrorist" policy, before some nutcase on public transportation decides the turbaned gentleman across the way looked at him suspiciously and blows the wog away? Given our resident social pathologies, testosterone poisoning and racism, it is going to happen. Remember Bernhard Goetz.
I do take some small encouragement from perusing the map: the states where the NRA considers the "right to carry" too restricted include most of those with developed public transportation.
UPDATE: Oh shit, Scotland Yard says the shooting was a mistake, a trajedy.
There's a part of me that sympathizes with the cops; they have a scary job to do. But someone is dead, gone forever.
