This is not something that happens. Robbers/thieves do not break into your home with you there to rob/beat/rape/kill you. If someone is going to predate on another person, they're going to do it somewhere NOT at a person's home, where they may have a gun/dog/significant other/witnesses. It's going to be done somewhere quiet, probably nearer to that person's turf, not the victim's turf.When I read about this it was something that was used. There are many ploys out there. One involves putting tape on your window. If you remove it they know your home. Others involve making you get out of your car to remove something from the windshield. Then BAM you're a victim.
This is retarded fear mongering by someone selling something, like a book, or home security.
The car one is the only even close to plausible scenario, but with that one, why would anyone bother to wait for you to get into your car, only to get back out? Why not simply snag you before you got into the damn car? Why target a car, not knowing the occupant (400lb black guy, 90 year old grandmother, police officer) rather than target a person specifically?
