Yeah, like that's
literally why the charge of "manslaughter" even exists. Cases like that one
specifically. It's basically, "I didn't MEAN to kill him, but... oops." That's exactly what happened and that's exactly what "manslaughter" is.
"Murder" implies
intent. Even second- or third-degree murder would suggest that the cop knelt on his neck purposely so that he WOULD die rather than just be restrained. In the case of third-degree it's a little bit murkier, because all that's necessary to fit that definition is "reckless disregard", but the term "murder" still implies intent.
And I - and a lot of people - have a VERY hard time believing that this cop - with a bunch of people watching and cameras on him and everything - MEANT to kill the guy by kneeling on him. I don't buy that at all.
Manslaughter would be applicable and acceptable. No problem there. Could've been more careful, and a guy died (who probably would have OD'ed anyway, but we're not supposed to dwell on that). So sure, charge and convict on manslaughter, the appropriate term. That's fine and fair.
The "murder" conviction was nothing more than serving the cop up as a "necessary sacrifice" so that a bunch of "progressive and well-meaning" people didn't "peacefully protest" a bunch of major cities into a smoking burnt-out husk. Any idiot could see it, and whether that was "necessary" or not, it still shows you exactly where we are right now. "We'd better convict this guy of a crime he technically isn't guilty of, or else."
But the cops are the Bad Guys.

Jesus. I don't even particularly like cops, I just end up having to defend them because Obvious Bullsh*t Is Obvious and it gets on my goddamn nerves.
