Went the wrong way down a one way to shortcut to our hotel.
Cop was adamant that he was going to take my license plates and write me a ticket for like $80 U.S.. he wouldn't directly state he wanted a bribe. I demanded he give me the ticket and the address to the station so I could pay the ticket but he refused. He kept wanting to know where I was from and I just ended up telling him that I am from Northern Mexico visiting playa on business. He told it was my lucky day and left.

If you speak solid Spanish and are white it's pretty easy to deal with them. I was the office errand boy in the Tijuana mission so it helps that I have substantial experience with these shake downs.
