I don't want to have a political debate with you, as like some here I find the polarization nauseating, BUT I do care about rights and the law and procedure. From the DOJ itself:
DOJ Bylaws (https://www.justice.gov/jm/1-16000-department-justice-policy-use-force):
Deadly force may not be used solely to prevent the escape of a fleeing suspect.
Firearms may not be discharged solely to disable moving vehicles. Specifically, firearms may not be discharged at a moving vehicle unless: (1) a person in the vehicle is threatening the officer or another person with deadly force by means other than the vehicle; or (2) the vehicle is operated in a manner that threatens to cause death or serious physical injury to the officer or others, and no other objectively reasonable means of defense appear to exist, which includes moving out of the path of the vehicle.
The officer very clearly was able to move out of the path of the vehicle in the video, therefore he violated the policy and the DOJ law as it relates to discharging a weapon.
It's important to know your rights, and the expectations of law enforcement. Fleeing a crime, that was a misdemeanor at best, does not allow for law enforcement to shoot you. It is black and white.
