We've seen plenty of this sort of behavior by the cops during this phony medical crisis--the father arrested for playing ball with his son in a park, the elderly couple relaxing on the beach who were told to scram, the lone surfer who was arrested, the harassment of churchgoers in Mississippi, and on and on. With the "defund the police" movement going full speed, cops need to quit alienating their supporters by acting like bullies.
I have a sign on my front lawn expressing support for our local police. Like each and every one of us, they need to avoid doing stupid things like the ones you mentioned.
Stupid is as stupid does.
Had I been there I might have said excuse me sir you almost look like a police officer because of the uniform you're wearing, but your behavior is that of a thug and a brute.
At this point I totally support complete defunding of these a-holes. Let people form their own protective cooperatives and militia.
