Dramatic video shows inside Pulse nightclub during mass shooting

Riveting bodycam video that captures the inside of the Pulse nightclub in Orlando, Florida after deputies rushed in during the mass shooting there last month has been released by the Orange County Sheriff's Office.

Authorities say 49 people were killed and dozens wounded by heavily armed gunman Omar Mateen at the popular Florida gay club in the worst mass shooting in U.S. history.

The video was aired by CBS Orlando affiliate WKMG-TV. Much of it is disturbing.
