According to the YouTube description:
After a school bus driver refused to open the door of the vehicle and allow a man onboard, he grabbed onto the hood of the vehicle. The incident was recorded on video. Baltimore County authorities now say the man has been arrested.
A man seen on video clinging to the front of a moving Baltimore County school bus has been arrested, police said. County police said the incident occurred around 3:15 p.m. Thursday in the area of Putty Hill and Hoerner avenues in Parkville.
W T actual F, right?
Well, there is a little more to the story... I don't know if it makes it any better, but apparently this man is a retired teacher and went nuts when a kid on the bus threw a Gatorade bottle at his car.
