Chicago is the murder capital of the US. You can be killed at random by flying bullets.
Ft.Worth TX is much safer. Chris Kyle was targeted by a guy whose mind was messed up by PTSD, not by random violence. Kyle was trying to help the guy. He turned his back and was shot in the back by a guy who wasn`t worthy of the trust.
That`s the point, cabbage head.
Another point is that I was saddened by his death whereas you were happy.
