Common sense tells us that you have created a nice little false dilemma here. Obviously there is a sane, rational, third choice, which is that there is no reason so choke a man to death on the street for selling cigarettes.
1) The policeman didn't choke him to dead. The fact he is telling them "I don't breathe" is telling he was breathing at the time and was conscious.
1-1) This imply any choke hold was not applied for more than a few seconds (not enough to do anything)
1-2) This imply any hold didn't prevent blood to reach the brain (he would pass out in few seconds and not be able to speak)
2) If he had collaborated with the police he would be get a ticket and would let go out. Or maybe arrested because he was on probation for previous sentences.
2-1) When he become uncooperative and then tried to go away, the cops (there were five and a black female sergeant) had no other option than to force him to submit.
2-2) Unless you advocate for policemen to have the power to arbitrarily enforce laws (different from "enforce arbitrary laws") the police could not avoid to give him a ticket or arrest him.
3) In the end the man died because he was very sick and his health failed him in a time of stress. Even his inability to comply with the orders and be reasonable could be referred to a chronic hypoxia, but health is not an excuse to break the laws.
What news papers and news shows and political hacks do not want is for people to understand that the first cause of this man dead is a stupid laws police was forced to enforce.
NY City/State have the highest taxes on cigarettes, so people smuggling cigarettes from nearby states and selling them on the streets outcompete the legal sellers of cigarettes.
The legal sellers then call the police to prevent this illegal competition from hurting their business.
Then the police have no other choice than enforce all laws, even the stupid ones.
The people guilt of this dead and of taking the freedom of people selling loose cigarettes on the street are the politicians people put in power at the state and city level.
Complaining how the police enforce these laws is like complaining about guns killing people without looking at the people holding the gun.
2. Right. There would be a good chance that he would be arrested and released on his own recognize by a judge.
3. - I can't really speak to how healthy he was, but he looked very much overweight which is generally an indication of someone not being healthy
