I've not been following the intricacies of the was it or was it not intentional debate,
Even if it legally mattered in securing conviction.

What my eyes and humanity tells me,
is that cop looked for all practical purposes
like a sadistic bully.

Almost like a great white hunter proudly dispatching his fatally wounded magnificent powerful big game trophy animal..

My subjective analysis is he continued restraining and tormenting Floyd
just to spite the concerned and distress onlookers.
The more they pleaded, the longer he continued brutalising his victim.
Just to show the audience he was the boss in control.
He has all the power they have none.

Turns out he got that badly wrong...
