While busting some moves at a club, FBI agent's gun "goes off", shoots other bar patron. Click through to the original news article; the video is not to be missed (kind of like the other patron's leg).
Update - Steve at the Pub, in the comments:
He should have checked his piece in with the government sponsored for-profit outfit called the Pistol And Carbine Orderly.
Now he'll be facing the Probity And Competence Office, where he'll face a Pretty Awkward Clarification Obligation, likely resulting in his Professional And Career Obituary, or what is to the rest of us, a Perfectly Acceptable Career Outcome.
I'm proud to announce that Steve is now Senior Vice President of Acronymns.
