This was posted on a local news site here in Indy. A Ball State Student was recording an interview about gun safety with a "gun expert" when the gun fired during the interview.

There is some footage of the interview and the "experts" reaction. The interview turned into a public service announcement and won the student an Emmy.

The title of the announcement was "Even Experts Make Mistakes" and "Make gun safety your business."
