The license plate frame law makes sense, especially in the case of less than observant cops. For example, I was driving my Ferrari 360 from a meeting in Mesa, AZ back to my home. While some of my cars reside at my home in Phoenix, they are registered in Ohio, where I am a permanent resident. I was stopped by a Mesa cop recently who ran my plates while folling me and stopped me to inform me that I was under arrest because my drivers license was suspended (according to LEADS). Soon another Mesa cop arrived to assist. The two intellectual giants stood behid my car looking at my plates for about five minutes. Coming from a background in law enforcement, I asked the officer which state he used when running the plates, he quickly replied, "Why, Arizona of course!" I told him to look at the plates again and let me know what state the car was registered in. He walked back looked again and said, "Oh, it's OHIO!". I told him to run the plates again. He returned to my car to ask me, "Are you Tim Cantwell?" LEADS flagged me as retired law enforcement, and he apologized profusely. The bad part of the whole story is that he never asked me for I.D., a driver's license, registration, etc., etc. He also did not ask if I was carrying a concealed weapon (which LEADS would have told him). Both cops blew their procedure totally! It did not give me a very confident feeling about how well we're protected in Arizona! The moral of the story is that the police need to see what state the plates are from!
