Seven of 51 guns discovered by TSA agents in airports across the country last week. Another week heavy on the self-shootings. We have 40 total listings, and 21 of them involve people accidentally shooting themselves. Seven of our listings involved law enforcement officers, active duty military, or security guards. Their seven accidents wounded three and killed two, including the astonishing death of a Marine guard posted at the entrance to Camp Lejeune, NC, accidentally shot by the other guard with whom he was standing duty. Speaking of astonishing stories, here's one I didn't include in the list, because it just doesn't fit the category: The Los Angeles County Sheriff's Department acknowledged Thursday that its deputies mistakenly shot and killed an aspiring TV producer earlier this week while responding to a stabbing and hostage standoff in West Hollywood.
