If that young mans parents hadnt instilled hate for white ppl and law enforcement into him and if that young man hadn't decided to murder those two troopers they would still be alive and he wouldn't be in prison for the rest of his life.
What the Troopers are just going to not go to call about a man brandishing a weapon and threatening others? That's their damn job, to protect and serve. And while yes they know it's a dangerous job, there was absolutely no reason for what happened that day. They were being respectful, kind and non confrontational. 
Your comment is ignorance and what is wrong with our society today at its best
