Kudos to St. Louis County Police Department...

They are offering active shooter training to ALL of their Officers, including the desk jockeys.

We used to do active shooter training a couple times a year, including with simunitions and full scenarios including responding from an off-site location several blocks away. We also used to have 40 hours of range training a year; now we're down to 16 at the very most.

We used to do it every 2-3 years. Lts. and above tended to skip the training. Everybody else did go.

It's required annual training in NJ, among a bunch of other stuff.

And every department has a handful of brass who was "too busy" for training. Ironically, they are usually the ones who do, literally, next to nothing, ever.
