I sure do, but there's some nuance here so I want to be careful how I say this.
First, the prosecution of "loosie" sales in New York City is a politically-driven initiative pushed down to the NYPD by former mayor Michael Bloomberg and current mayor Bill de Blasio. New York State charges $4.35 in taxes for a pack of cigarettes, plus an additional $1.60 imposed by the city (it used to be $0.08 until Bloomberg raised it in 2002). This has driven the retail price of cigarettes in New York over $13 per pack, opening the doors for the mafia, gangs, and other criminals to smuggle cartons in from low tax jurisdictions and make a killing selling "loosies" below retail. Loosies have made a significant dent in the city and state tax revenues, so De Blasio has ordered the NYPD to crack down on their sales. Thus, this was essentially an overbearing and violent tax-collecting effort more than enforcement of petty misdemeanor laws.
This has been a documented issue for years:

That said, a business owner originally reported Garner because he (the business owner) felt that his retail sales of cigarettes were being harmed by Garner's loosie sales. With a citizen complaint, the police had no choice but to respond and address the issue. They weren't out to get Garner because of any personal vendetta against him, but because a complaint had been filed by a citizen.
Finally, I've said this before and I'll repeat it: Garner would not have been arrested nor taken down by the police if he had complied with their requests in a calm and reasonable manner instead of acting outraged that he was being "harassed."
So yes, I think two things were unreasonable in this case, but neither one is the fault of the NYPD. First, it is ridiculous that New York imposes a near-100% tax on the sales of cigarettes and then issues marching orders to the NYPD to make sure they collect. This is the fault of politicians, not the officers.
Second, it would normally be unreasonable to tackle and cuff a man for the sale of untaxed cigarettes, but that particular set of circumstances was brought on by Garner's reaction to the initial, peaceable contact.
