Should the bodycam footage from the NZ shooting be used for training?

I think if it is used by law enforcement organizations or Homeland Security to train first responders or somehow make the public safer, it should be used. It should not be hung out n the World Wide Web for everyone to gawk at. This is extremist erotica, whether you are a white supremacist looking for encouragement or an Islamic extremist looking for justification for something insidious to justify the heinous thing you are about to do or a GP whack-a-doodle window shopping for their big moment in the sun.

I don't think this would be an effective tool for teaching an active suspect session. Specifically produced training videos balance the horror and the decency and should be paired with 1. Your organization's battle drill (beyond glib the run hide fight) and 2. The physical security measures in place.

Having been in a law enforcement position, no. Watching a video of how police and first responders reacted does not help new trainees. It is a perspective they have a hard time relating to because it is just an abstract movie to them. What works BETTER, is let (not force) the ones there to rewatch what happened. Have them think like a trainer to analyze their own reactions and what could have done better. Then stick the ones who learned the most in mentor ship or leadership roles of training.

If and only if, it has real applications to the trainee's battle drills - either pro (do this) or con (don't do that). Definitely not just as a "watch what happened and tell me what you think" exercise.
