We just don't need any more "how not to get raped and murdered" advice. Every woman and girl I'm sure knows all the what to wear, have your hair, where to go, who to go with, what to drink, how to hold your drink, where to park, how to unlock your car, where to sit on public transport, how to respond to men if you don't want to get raped and murdered advice. How not to get raped and murdered by the police advice doesn't help.
Advice on how to increase the chance of your body being recovered, dna evidence being found or your attacker being prosecuted (text your location, take a photo of his number plate, position yourself near cameras, scratch him) is particularly unwelcome.
