Notice on car (not a joke)   
 Just last weekend on Friday night we parked in a public
 parking area. As we drove away I noticed a sticker on the
 rear window of the car. When I took it off after I got home,
 it was a receipt for petrol. Luckily my friend told me not to
 stop as it could be someone waiting for me to get out of the
 car. 
  
 Then we received this email yesterday:
 'WARNING FROM POLICE BEWARE OF PAPER ON THE BACK WINDOW OF YOUR VEHICLE--NEW WAY TO DO CAR JACKINGS (NOT A JOKE)'
  
 You walk across the car park, unlock your car and get inside. You start the engine and shift into Reverse.
 When you look into the rearview mirror to back out of your
 parking space, you notice a piece of paper stuck to the middle
 of the rear window. 
 So, you shift into neutral, unlock your
 doors, and jump out of your car to remove that paper (or
 whatever it is) that is obstructing your view. 
 When you reach the back of your car, that is when the carjackers appear out of nowhere, jump into your car and take off. They practically mow you down as they speed off in your car.
 And guess what, ladies? I bet your purse is still in the car.
 So now the carjacker has your car, your home address, your
 money, and your keys. Your home and your whole identity are
 now compromised!
  
 BEWARE OF THIS NEW SCHEME THAT IS NOW BEING USED.
  
 If you see a piece of paper stuck to your back window, just
 drive away. Remove the paper later. And be thankful that you
 read this e-mail. I hope you will forward this to friends and
 family, especially to women. A purse contains all kinds of
 personal information and identification documents, and you
 certainly do NOT want this to fall into the wrong hands.
  
 Please pass this on.
