I just saw a comedy segment in which Carlos Mencia tried to uncover the meaning behind a highway sign that’s unique to San Diego county. In the course of his quest, he talked to a representative from law enforcement who was adamant that it wasn’t meant to depict anything other than that it’s dangerous for people to cross the interstate. No, it wasn’t about immigrants. No, it wouldn’t be proper for signs to be meant for any “ethnicity” or race. That guy obviously hadn’t seen or heard of this, the study that prompted San Diego county to design and put up their unique road signs in the hopes that the body count would decrease.
