It’s not a disingenuous question. Sure, you are correct insofar as you identify refusal to submit to arrest as the immediate cause of the confrontation and all subsequent events flowing from that.
But, it doesn’t begin and end there, does it?
Surely you can’t be suggesting that a society where police can arrest and detain anyone with force on almost a whim is one we ought to celebrate and encourage.
Physical arrest ought to be used only when necessary - and not for crimes such as over-flushing a toilet or selling an odd cigarette or two on the street. Cops have better things to do, and we as taxpayers have better things to do with our money than to fund this sort of waste.
You persist in understating the crime. This wasn’t selling an odd cig or two, this was persistent business for which he had been apprehended some 8 times.
And this wasn’t merely being arrested for a debatable crime, this was active statement and act of refusal to comply.
