I'm not saying I could of done better in that particular set of circumstances. My only somewhat relevant experience is infantry based anyhow and we had close air support.

It doesn't mean the officer and his department can't look at the video and try and get better at their job. I'm not trying to denigrate the officer at all as he managed a tough situation and survived, but he would be foolish IMO if he doesn't try to learn from it and get better at his job.

Do you think the department your son works for looked at what happened (in the incident you linked) and tried to learn from it?

I'm fairly certain that department training, SOPs and equipment are driven in part by actual incidents and also possible scenarios that they figure they are likely to encounter. Unfortunately sometimes those lessons learned are purchased with blood.
