This is a sad video to watch because those officers spent 7 minutes trying to desculate the situation with verbal commands and then less lethal tools. It was as if they were hesitant to go full hands on and use real physical force to gain compliance albeit the suspect was passive resistive for a good portion of that encounter. I see today's young LE really having difficulties in making quick decisions on when to use force and how much force to use. This is because they will be judged in the media and by politicians who know nothing about police work. This will lead to officers being hesitant to use appropriate force and will result in their injuries or death as noted in the video.
You could see that encounter going sideways pretty much from the get-go. That dude was showing several signs that something was up and things were not going to end well. There is a spot in hell for people like him. POS. Sad deal for the officers who were unnecessarily shot and killed. Damn.
