That's the British way, and it will very likely become the American way if the Leftists here are able to achieve their ends - though naturally, our Leftist politicians will retain their armed guards. But for the rest of the populace, the "little people", as it were, the advice handed out to anyone finding themselves under attack will be succinct: chill. Try not to defend yourself too strenuously. And if you witness an assault, do not rush to the aid of the victim.
“The BBC offers this advice for anyone in Britain who is attacked on the street: You are permitted to protect yourself with a briefcase, a handbag, or keys. You should shout ‘Call the Police’ rather than ‘Help.’ Bystanders are not to help. They have been taught to leave such matters to the professionals. If you manage to knock your attacker down, you must not hit him again or you risk being charged with assault.”
Fear not, citizen; government is there. And the media, as well.
Small wonder that gun and ammunition sales are skyrocketing here.
