Cops aren’t trained for shooting to injure, they are trained to shoot center mass because it is the largest part of the body which coincidentally contains a large amount of vital organs. Plus a dangerous individual who is injured is still dangerous. Tasers wouldn’t have worked because of the thick winter wear. They could have tackled him… But that leaves them open to being fired upon from the people in the truck.
Where the final confrontation took place, there were not a lot of options.
