We live in a fallen, broken society. You can't just go about your business without someone trying to steal from you.
In the case of this man from Kennewick, Washington, that business was burglary. He parked his truck and, uh, liberated some items from a shop. Being a trusting soul, he had left his keys on the seat.
When the burglar came back to make a getaway, he saw someone driving off with it. This video shows him chasing after the truck thief at the 1:21 mark.
So the victim did what any sensible thief would do: he called the police.
When police reviewed surveillance footage, they found that their caller had broken into the shop. They arrested him.
According to KEPR-TV News, they haven't found his truck. So the whole burglary job has been a total loss.
