They started doing these cars in a the late 90s I belive the shows just put it on tv that is all they did not come up with the idea.You can not be entrapped when you are trying to steal a car, you are trying to seatl a car you just stole one that you cant steal

. It is just like undercover drug buys a sales it is legit so long as they dont entrap and willingly comitting crime is not entrapment.
I saw on the Bait Car show a few times people taking the keys and calling the police to report an unattended (unaware it was a bait car) car!

They set these cars up in high auto theft areas. I hate M..... F.....s that steal.Caught a guy once trying to jimmy my car had my buddy cover me I while snuck up and punched the guy in the back of the head so hard his face smacked the side window and he dropped out cold:rotfl: took his jimmy bar and threw in a rentention pond and left his dazed ass sitting in the parking lot some store security guy came up and told us to leave and that he would "take care" of our friend. I wonder what ever happended to the punk his face was bleeding pretty bad I must have broken his nose.
