There was an unintentional discharge at Lt Allan's funeral.
News report: http://www.wthr.com/article/accidental- ... o-hospital
This forum thread discusses the incident, and has some commentary, including a picture of the type of handgun and holster involved. Some of the thread participants are police officers, including the one who posted the picture (and was at the funeral).https://www.ingunowners.com/forums/gene ... neral.html
Pulling pieces from the news report and the thread, it appears
that a male officer or deputy was seated, but turned around talking to a female deputy in the row behind him. He had a Glock with a TLR1 light attached in a department approved Safariland ALS holster designed for that configuration. When he stood up the handgun discharged, went through the bottom of the holster and a chair seat, and grazed the leg of the female deputy.
If you go look at the pictures in the thread, the poster show that in fact he can insert his finger from the back of the holster all the way to the trigger, and as he notes, if a finger can get in so can something else.
The trigger appears to be within the holster, but exposed somewhat because the holster has to leave room for the mounted light to pass through.
If you carry a light on your handgun, you might want to take a close look at your gun/light/holster configuration.
