I got an e mail from a police officer friend of mine about a new carjacking method. The 'jackers will stick a piece of paper on the rear window of your car at a shopping mall or store or wherever. When you back out of your parking spot it'll be situated so you can't help but see it while checking behind you. IGNORE IT! Most people will get out of the car to see what it is. That's when they'll pounce. Your car is running, ladies will have their purses in the car, all your purchases will be there, etc. In the purse they'll likely find house keys along with a drivers license with your address, credit cards, Social Security card, money. You might have a gun between the seats.
The recommended action is to drive on, maybe all the way home or at least far enough away before you check what the paper says. Practice a heightened situation awareness & make sure nobody is following you. Call the local PD & let them know what you suspect.
