It's baffling, tbh. But, in all consideration, maybe they had their reasons to try to stop him, but not like that. My only guess is that they either didn't like the person that needed help and wanted them to od or maybe that person was their friend and voiced their wishes to them of basically a dnr or something. Some of the addicted people I've known have wished for death and would voice that. I'm definitely not condoning the attacker's actions at all and the police were there doing their job. Just thinking of a reason why is all. But then again, maybe the attacker hated cops. Regardless, tragic all around.
