Someone stole my expired registration... should I be worried?

Car got broken into last night... well, sort of. I left it unlocked on accident. But there was nothing of value, so they just ransacked my center console, and made off with the user manual, a backpack with an old outdated textbook from school, and the expired registration paperwork. They left my (current) insurance paperwork and didnt bother going in my trunk, which makes no sense to me, but whatever. My only real concerns were the mess they left (I had just cleaned my car...), and the expired registration. Can they use it for anything? This is in Florida, if that makes a difference. Any info or help is appreciated. via /r/cars http://ift.tt/2sE5w0H
