The guy was pissed out of his head, waving a loaded shotgun out of the window and had already fired a couple at the Police. He's a serious life threatening danger to both the Police & public. I really don't know what else the Police could have done other than blow him away.
If he was a scrote from the East End of London rather than a gushed up Chelsea Barrister who went to Oxford would there be all this fuss ?
