> his movement could be interpreted as a movement to the officers firearm <
I guess well have to agree to disagree on this one. If the old guy was empty-handed, I might be able to see your point. But he was holding something. And he moved his hand above the officers arm. Not below it, where the cops gun was.
And if the cop really thought that the old guy was going for his gun, why wasnt the old guy cuffed and arrested? Why did everyone just walk on past him?
Anyway, as I see it:
Old guy: Stupid.
Cops: Too hard a shove, but no harm was meant. Hand out a few days suspension, and thats it.
Yes, he was holding something - it was a TAZER disguised as a cell phone. ANTIFA agitators use innocent looking people to do their work for them. Sorta like ISIS.
The officers in this instance are not required to, nor should they be expected to evaluate the total threat, the age, the gender, or the physical abilities of the person approaching them and not obeying their lawful commands. If they guess wrong, the officer goes to the morgue at the close of day, instead of his home.
