He did not crash a roadblock, he swerved into a snowbank. He has women in the car. Swerving save the two women. After being shot three times and bleeding out, instead providing assistance OSP empties a hand gun into his body I guess they were yelling at him to get up on his knees and he didn’t obey. OSP says to themselves, he is not obeying lets put 6 more holes in him then we can murder the women. That will lots more fun.
If the police simply wanted to kill everyone there then everyone there would have been dead. Finicum died because he didn't want to go to jail, and yet by his actions he put himself on a course where he was headed to jail. If he had simply done what the other vehicle did, and what everyone else in his vehicle did, he'd be alive, but in jail. Your fantasies about the police seeking to murder all of them are your own sick fantasies, and have no basis in what occurred.
