Now it's always been my impression that the police like to have the element of surprise in their favor. Suddenly there's a police car coming up behind you, or appearing out of nowhere. That's why I was surprised by something I saw when I was meeting with our Latin American team in Guadalajara, Mexico. At night we were driving around with our Director, David Isais and we saw a police car in front of us. Now, he was in no particular hurry, but his lights were flashing - and David said, "You know the police cars here do that all the time, they leave their lights on whether they are on call, or not." Now, that's an interesting approach to law enforcement - let them know you're coming.
