I think they run the license AFTER they stop you, not before. They usually don't have time to run the plate while they are in pursuit of stopping a vehicle. That's the reason you see stories of officers getting in fights and sometimes shot at traffic stops. They don't know what they got until they run the drivers license. The plate doesn't link to the crime computer, the drivers license does. The plate just shows who owns the car.
If your DL says one thing, and the plated says another, expect some time in the back of the squad car. LOL!
Actually, your license plate is run as soon as he/she has you pulled over. Not when you are being pursued? And it is the LICENSE PLATE that tells the officer if that vehicle is registered to a CHL. That is what the Sheriff's Dept. told me when I picked up my CHL the first time. After he/she has observed your DL or CHL, he may still run your information to check on wants and warrants. And probably will to see what kind of driving record you have as well. Just because you have a CHL, doesn't mean you didn't just commit some other crime recently? What I mean is...just because they know your a CHL by running your license plate, and by viewing your CHL, doesn't mean you didn't just beat your wife that day, or commit any other crime that would disqualify you from being a legally armed citizen any longer?
So by running your plate, and then your DL, and or your CHL; LE can check and double check any information that has to do with you, and your vehicle?
YOU SAID, "That's the reason you see stories of officers getting in fights and sometimes shot at traffic stops. They don't know what they got until they run the drivers license." I'm sorry, but I don't believe this to be the case at all? The reason, I believe you see stories of officers getting in fights and sometimes shot at traffic stops, is because they are dealing with criminals, not law abiding citizens? And it doesn't matter at that point whether they run the drivers license or not, does it?
Too many scenarios can be debated at a traffic stop. I'm certainly not going to entertain the idea. I just wanted to share with you that YES in OHIO they know you are CHL when they run your plate. They already have your name, address, etc... That's just the plate. Then they may ask to see your DL, registration, maybe even your CHL?
