tailgate picture is offensive

A truck detailer in Waco, TX is getting some flack about a decal they made.  It's a picture of a woman tied up and crumpled in a heap.  They put it on the back of a company truck and it was seen all over town.  It was also placed on their facebook page and has gotten a lot of messages both good and bad.  The company says that it was done as a joke.  Seriously? This is not something to joke about.  tasteless decal
