It MIGHT be less traumatic IF the person that was killed had a weapon.
So, how do we make sure that no one shoots until it's absolutely certain that someone has to be shot?
We can't.
Just two days ago we showed you the video of three teens in Texas that refused to comply with a police officer's commands. That officer came within a hair's breadth of opening fire on the closest teen before the 17-year-old finally complied with his commands.
We can't go around shooting people just because they don't do exactly what you say, as quickly as you may want.
