I can nearly 100% guarantee that what's happening. Have you ever done a ride-along with a police officer -- especially in the last two years? With the advent of efficient wireless db access to the police databases, I can tell you that every single police officer runs the plates on every single intersection that they come to. When they spot an out-of-state plate they are more or less obligated, depending upon their standing rules of operations, to check for a few more things. It's actually kinda stunning how much multi-tasking is going on when a police cruiser stops for a red light or a stop sign....
There's no question that police officers use a variety of indicators when deciding whether they should pull someone over -- but on average, I know that in Las Vegas, my plates have probably been run at least a dozen times a day -- and most departments work on a similar production level.I doubt that. I am a dark-skinned male in my late 20’s driving a late-model Buick with out-of-state plates.
