Well we're talking about a specific crime here, fleeing in a stolen vehicle. Hardly worth a firing squad. Did you actually see the videos? One fine officer decides its a bright idea to jump in front of a moving vehicle. Another shows that the kid merely bumped a squad car, then the officer decided to open fire which I can only guess is because the kid was getting away. You're not allowed to execute someone just because they're getting away.
If I was the captain I would fire the one that jumped in front of the care because he obviously isn't bright enough to look out for his own wellbeing, let alone the wellbeing of others
