You can't know until you been in this type of situation, i remember years ago watching a documentary on policing, they brought in 10 people and put them in situations cops are in daily, gave them a weapon with blanks, a real time criminal situation, and every single person they chose disliked the police. Every person in these situations shot their guns every single time, and most of them had a different opinion on situations that take place in the news involving cops, every one of them changed their views on these types of situations, its hard to regulate situations like this when people are screaming all around you especially when there are dozens of people surrounding you screaming and having firearms involved. Like i said its easy to watch videos in slow motion and come to a conclusion but its much different when these people actually are put in these types of situations and see it first hand. When you go out daily and risk your life and have people screaming and gun shots going off its a different story. One mistake by an officer and its game over , their life is gone and their families lose a loved one.
Again, I understand this well. I have a best friend who is a state trooper. I have law enforcement in my family. I know the challenges well.
With all of this said, it does not exempt him from being held accountable. A man who was disarmed, on the ground and posing no threat was shot in the back/head. There is no excuse for that. That agent clearly lacked certain skills and is unqualified to be in that role. Period.
