You'd think as a first responder, this cop would've known better, but some people just prefer learning the hard way.

People become cops for a lot of different reasons, but judging by this rookie's behavior I'm guessing the idea of having authority over others was the biggest reason he signed on. Soon as he approaches the scene of an accident, he starts acting like he's in charge... all while keeping the real pros from being able to do their jobs.

Thankfully, his sergeant was also on the scene and had absolutely no issue with his junior officer getting taught an expensive lesson!
