So we can update - know all our legal rights, flag down a bus and phone 999 - to the rules when a lone plain clothes policeman want to arrest you. Good to know.
I suppose we'll add this to the other rules, don't walk alone at night, don't wear the wrong clothes, don't drink too much, don't forget to take your drink to the toilet, don't piss a man off by rejecting him too forcefully in case you humiliate him and he is forced to punch you in the face and don't be too polite or you are leading him on, don't forget to ring your friends when you get home in a taxi, never forget to pretend someone is in the house when a strange guy knocks on your door at night.
Apparently the police believe telling women these Mickey Mouse rules of safety is more effective than telling men not to rape, batter, strangle and murder women. Or so you would believe from their communications.
