Disturbing?

Hardly.

PHILADELPHIA -- The owner of a small breakfast restaurant who has been robbed in the past killed one alleged robber and injured another during a robbery gone bad in Philadelphia Thursday morning, police said. After several rounds were fired, a witness captured the aftermath on his daughter's cell phone video recorded.

The video could be considered distrubing to some.

The video in question shows an armed citizen defending his family and detaining an armed robbery suspect at gunpoint.

"Disturbing"? Try "fucking glorious"!
