Body camera footage shows the dramatic rescue of an FBI agent whose SUV was left hanging over the edge of the I-794 overpass in downtown Milwaukee Monday morning during rush hour traffic. The FBI agent was on her way to work. The driver of another car who caused the crash told deputies he was trying to avoid a driver who slammed on the brakes in front of him. A Milwaukee County Sheriff's deputy smashed the back window of the agent's SUV so she could safely crawl out after a frightening crash lef
