They (Arvada) don't have body cams, so if that's what you're waiting on like it's some kind of end all it's not coming.
I believe it came from one of their briefings. I'm not saying that makes it any less tragic, it's still a shit sandwich.
Here's the difference, though, LE has been getting active shooter training since Columbine, I'm glad CCW is starting to get involved but let's be realistic...
IF they're going to step up in these situations, a 10hr class and a permit ain't going to cut it.
This situations are so dangerous I'm not sure we have the vocabulary to describe them and to expect citizens with a day or a weekend of training to jump into them and interact with LE seamlessly and without tragedy is fucking ridiculous.
I'd like to see more citizens invited to LE active shooter training events and set scenarios like this up. Give the citizens opportunities for stress innoculation if they plan to respond and make sure they put the gun down when the shooting is over so when the cops come charging in they're not mistaken for the bad guy.
IMO there's no way to train this away, it's always going to happen, you just flat out can't be holding a gun when everyone shows up looking for a bad guy holding a gun
