What's wrong with people today?  Why do we act the way we do?  Is society becoming less civilized? These are just a few of the questions you may have after you watch this video of a brutal sledgehammer attack in a Philadelphia parking lot.

Surveillance video posted to YouTube shows a man in a red truck following a silver car into the parking lot of an office building Philadelphia's Port Richmond section. The man in the truck gets out and smashes the windows of the SUV with a sledgehammer.

When the SUV driver attempts to leave the parking lot, the passenger of the SUV falls out. he driver of the truck hits the passenger with a sledgehammer and then breaks the rear window out of the SUV. The video is very disturbing and bizarre.

What's also disturbing is that this guy is still on the loose, and as of Wednesday night, Philly Police don't have any leads. If you have any information, call police at  215-686-TIPS.
