New Carjacking Scam

Last Friday night we parked in a public parking area to go to a restaurant. Later, when we drove away I noticed a piece of paper stuck to the rear window of the car. My friend told me not to get out and remove it until I got home because it could be a trick currently used by carjackers.
Coincidentally, a day or two later I received this email.

Police Warning (applies to men and women)

Beware of paper on the rear window of your vehicle - new carjacking trick

Heads up everyone! Please circulate this warning....Hypothetically,you're walking to your car in a parking lot.You unlock your car and get inside.You start your engine and shift into reverse.When you look into the rearview mirror to back out, you notice a piece of paper stuck to the middle of the rear window. It's obstructing your vision. So, you shift into park, unlock the doors and jump out of your car to remove it.When you reach the back of your vehicle,carjackers appear out of nowhere, jump into your still running car and burn rubber out of there.You'll be lucky if they don't back into you first to disable you.
And, guess what, ladies? Your purse is still inside the car with all your money, credit cards and ID, not to mention your address and house keys, if they feel like a little burglary later or perhaps an identity theft.Your home and identity are completely compromised.

WHAT TO DO??
If you spot a piece of paper on your window,drive away and leave it there until you get home.Be safe... and pass this information on to your friends and loved ones, especially the women.Their purses contain all their personal information and they are the preferred targets....BE ON GUARD.

Your concerned friend Jeannie.
