Somehow, I don't get the impression that you were suggesting instruction and teaching in your comment, unless that means strike first and ask questions later.

Police also need to respect the citizens that pay their salaries. Yes, it is a difficult job, but they chose to serve and protect. I see nothing about protection when you are kicking someone as the lay on the ground.

If someone pulls a weapon on a police officer, I have no problem with an officer shooting them dead right there. I see no evidence that warrants this type of behavior.
