When saying something like "his actions were necessary" you DO have to consider all hypothetical situations, because you are telling everyone listening to perform the same action in a similar situation. Standing in front of a car as a means to deter it from leaving may work for the mass majority of the population, but you don't plan for the mass majority, you plan for the 1 out of 1000 that will leave you laying crippled on the side of the road. Why are cops observant of driver and passenger actions when they are conducting a stop? If we planned for the mass majority, they should casually stroll up to the window. We plan of the freak occurrence where someone doesn't shift their car into park, is hiding something, is preparing to attack the officer, or anything else that is not "normal". We cheer on this cop because he took down an arrogant asshole in a Ferrari....big deal, he got his foot "run over" in the process and it could have been far worse.
