I would find it very embarrassing and emasculating that I could not handle that type of subject as a viral young man.
You imply that you cannot be knocked over easily in the midst of a physical confrontation. Especially by an older man. Yet if you watch the video, you see it happen. It isn't that hard to do, especially if the younger 'officer' doesn't expect it coming from a 70+ year old man. It appears that the old man shoved backwards at the right time and caught the officer off balance.
“You don’t know what the man said to the officer.”
And it wasn’t recorded because of a Thug cop listening to Rapp Music. Any cop caught listening to that on duty should be fired because then we already know what kind of person they are.
