He killed 3 cops. What do you expect?
I expect cops to take a suspect into custody, but not risk their own lives.
Jayland Walker fired a gun and was wearing a sky mask and appeared to be going for a weapon when the cops facilitated his Suicide by Cop.
The part you leave out with Lance Storz is that he had his wife and daughter in the house with him during the shoot-out with police. He was firing from a fortified position and had body armor on.
