Once the arrest procedure has been initiated it has to be followed through, no matter what the offense was. Reacting to resisting with "oh well we don't have to arrest him after all" would be a bad decision, especially since the resisting itself gives you yet another offense.
Frankly, I think such a ridiculously minor offense should not be an arrestable offense in the first place, and should be handled with a ticket which could have been issued without ever touching him.
And if it was just the "loosies" they probably would have done just that. But he was out on bail not only for selling "loosies" but also driving without license, false personation and marijuana possession. As such they had to arrest him for violating bail.
But if an arrest was absolutely required for this massive tax fraud case, why couldn't the police issue a "citation in lieu of arrest". Most states give police this option in non-violent situations like this.
Again, bail violation.
Or perhaps instead of surrounding him and poking at him, the police could have chosen to diffuse the situation, maybe even let him walk away, and then gotten a warrant to arrest him later.
Oh, was the time and place not convenient for him. Is NYPD in business catering to such requests normally?
I don't think they could do that because I don't think they even had probable cause that he was selling "loosies" at that time, but IF they had evidence of a crime there was no urgency to arrest him immediately. He wasn't being a danger to anyone and he wasn't going anywhere.
If they suspected he had evidence on his person then he could have destroyed it if allowed to walk away.
Instead, they killed a man on the mere suspicion of selling cigarettes without paying the state taxes on those cigarettes. Does this really seem to you to be a valid situation for deadly force? Seriously, you claim to lean Libertarian. Do you really think the non-violent, and in this case extremely petty, crime of tax evasion requires a deadly force response from police?
But it wasn't deadly force, not ordinarily. They had no reason to suspect the arrest would turn deadly. But sometimes shit happens.
