Ticking time bombs. A 12-year-old boy was killed when a grenade left over from World War two exploded in his bedroom. And it’s not an isolated case. There are countless grenades sitting around that could go off with one wrong move. And parents outraged! A competition winning high school dance team was practicing outside... When, as a punishment, their coach allegedly made a number of the girls crawl on a running track that was scorching hot. They ended up with painful blisters. Plus, he's still at it! Jimmy Kimmel returned to the airwaves for his second show since his suspension was lifted. And if you thought Jimmy was going to be kinder and gentler when it comes to President Trump... Think again. And how vulnerable are we? The ICE detention center gunman...  Took his shots from a nearby roof. This in the wake of an assassin shooting and killing Charlie Kirk from a roof approximately 142 yards away. Many are asking -- how secure are our rooftops?
