A video obtained by local television stations shows the lanky male agent -- a crowd off to his side -- putting in some energetic dance moves before executing his backflip.
Unfortunately, the move was less of a crowd-pleaser than intended when his gun fell out of his trousers. The agent couldn't catch it in time before it went off and shot a man in the lower leg.
The shooting victim was recovering in hospital from non-life-threatening injuries, the local ABC television affiliate said.
The agent was taken to police headquarters and then released to an FBI supervisor.
