Fox said about an hour ago that it hit someone in the crowd and fell to the floor and no one was hurt. Do you think from this that it was a "dummy" ?
Hubby said it had to be a dud...when you pull the pin and release the lever, you have about 3 to 5 secs before they explode..
I doubt the validity of the story, or maybe just a toy grenade. Real grenades are very simple devices and once the pin is pulled, they will explode
