Whoever thinks this should have been handled differently, please explain how and why. Put yourself in the troopers driver seat. What would you do when you exited the car and confronted the man you just had a pursuit with not knowing if he had any weapons on him? Remember you have no backup. 
You can b*tch all you want and say, "the trooper broke the guys clavicle and fractured his rib." Really?! That idiot did it to himself. None of this would have happened if he didn't flee from the cop. He could have easily killed himself or even killed someone else for his stupid actions. Lots of lives are put at risk in these situations. This isn't a pursuit in a "movie". 
You can play the "cop needs to keep his emotions in check card" all you want. Reality is though, they are human just like you and I. I'm sure this trooper has seen some bad wrecks in 22 years. You try keeping your emotions in check when you see a young boy/girl dead due to someone's actions like this.
