A U.S. Marshal managed to shoot himself in the butt, and another officer in the ankle, while holstering his pistol after dropping off a prisoner early this month.
As David Codrea said, it's a "Two-Fer".
The full video is available here, while an edited, but larger-format segment of the video is available from KVIA-TV here.
The rest of this is pure speculation on my part.
It appears that, while holstering his pistol, the Marshal allowed some portion of his anatomy (his finger?) or his apparel (the tail of his snazzy photographer's vest?) to come between the holster and the trigger. When he jammed the pistol into the holster, that darned thing "Just ... went off!" (Imagine that? Darned guns, they do that a lot. "Not my fault!")
I'm obviously playing in my mind the scene where the U.S. Marshal attempts to justify the 'incident' to his superiors.
The thing is, this is exactly the kind of incident that is addressed (and almost universally avoided) by training competitors in the many "Practical" shooting venues: IPSC, USPSA, IDPA -- they all emphasize that you absolutely must keep your booger-hook off the bang-switch while holstering.
I know, I know. This guy must deliver prisoners on a daily basis, and he must always be required to deposit his pistol in the lock-down area. He probably re-holsters his pistol several times a day, five days a week.
Still, he screwed up.
What will you bet that the U.S. Marshal's Service institutes, within the next 30 days, a program of remedial training in "Safe Holstering" for all agents?
They could save themselves a lot of training time and expense if they just required their agents to enroll in a Practical Shooting sport, and attend at least one match each month.
RULE I: ALL GUNS ARE ALWAYS LOADED
RULE II: NEVER LET THE MUZZLE COVER ANYTHING YOU ARE NOT WILLING TO DESTROY
RULE III: KEEP YOUR FINGER OFF THE TRIGGER UNTIL YOUR SIGHTS ARE ON THE TARGET
RULE IV: BE SURE OF YOUR TARGET
Question: How many of these rules are violated here?
Answer: at least three; perhaps all four.
Darned FBI-slant holsters, anyway.
