Another simple piece of advice to ladies. Keep your keys in your pockets. My mother used to get on my case all the time, because I did. Then somebody stole her purse. After that she quit pointing out that they spoiled the line of my clothing, and made holes in the pockets, and kept her keys in her pockets too.
Keep car and housekeys separate. That way the creep who takes your car can't come into your house.
A policeman adviced me that I should swear if threatenned. One night I met a creep, who grabbed the hem of my skirt on the 6th Street Bridge. I swore like a Marine Drill Sergeant. He walked off in disgust and raped somebody else that night.
