This oldie-but-goody video of a DEA agent shooting himself in the foot while lecturing about gun safety is a painful reminder of the importance of a good, secure gun holster.

In the video, you will see that he accidentally pulls the trigger while trying to put his gun back in its holster. From the video: “I’m the only one in the room professional enough that I know of to carry this Glock .40. I’m the only … (shoots himself and pauses) … Is everybody all right?”

Although we’re constantly amazed by his ability to not freak out after being shot, we’re equally amazed by his utter stupidity. Granted accidents do happen, things like this probably shouldn’t in a classroom filled with students learning about gun safety.

In 2006, two years after that nearly fatal mistake, the injured agent in the video, Lee Paige, became internationally infamous and filed a suit against the government over his humiliation. According to The Smoking Gun, Mr. Paige claimed that the DEA was responsible for the video’s distribution that was widely circulated online and on TV, which ultimately led to public shame and kept him from taking part in future undercover operations and motivational lectures.

“And I actually had an accident where I almost hit my femoral artery, and I could have died,” Mr. Paige said in a 2006 CNN interview. “The physician indicated I would have died in 22 seconds had that happened. So, and also, my — my safety and my ability to do my job is compromised.”

Below is an excerpt of Mr. Paige discussing the incident on ABC.
