McDonald's has video cameras pointing at every inch of their property 24/7. All they need is a timestamp from the AP and they'll go find your license plate in the parking lot on the surveillance tapes.
What kind of idiot drives a car with a valid personal license plate while committing crime?
I don't even drive a car when I'm selling shit on craigslist for fear they'll look up the plate and do dumb shit when they're mad the drill I sold them has normal battery life.
Most criminals (they're risk takers) don't really think these things out and a large percentage of them get away all the time. Stuff goes wrong, footage goes missing, cameras don't work, prosecution bungles some rules, etc.
