The only similarity between the two situations was that the victims acted like morons. One attacked a man with a shotgun, the other stepped out of his vehicle with a shotgun. I don’t care who’s right or wrong, you’re asking for it. Otherwise one was self defense and the other guy was shot in the back.
Something to ponder: Instead of getting out, standing completely still with the shotgun in the air, the guy starts walking toward the front of his car. One, maybe two more steps, the car door is between the armed suspect and the officer(s). 2 or 3 steps and they guy has the entire car between him and the officers.
For the benefit of those born without an imagination or empathy:
Not a police officer. Contact happens just as you see it from the time the car door opens. Contact was initiated because of trespassing. Citizen is to the front left of the camera, gun holstered. Everything else remains the same. No sound.
