Like everyone else posting on this thread, I am not a Judge, so I can't give a definitive answer to that question.
However, as a lay person, I agree with the following assessment.
If you believe the police report (and this is an essay about matters of law rather than matters of fact), then Professor Gates probably satisfied the criteria of Model Penal Code s. 250.2: (1) by shouting insults at the cop from his front porch, and even though the front porch itself is not a public place, it was sufficiently close to the public sidewalk and street so that "persons in a place to which the public or a substantial group has access" were affected.

The facts in the
Mulvey case which I linked in another post are as follows: the police arrived at a man's house to serve him with an out-of-state warrant for his arrest. The man was on property with a large driveway and a some fencing. The man told the officers to get off the property, yelling many times I believe, and basically put up a feeble resisting arrest (battery charges also ensued along with the disorderly charge). The jury acquitted him of all his other charges and the only issue left to appeal was the "disorderly" conduct.
Since the incident happened at a residence it was deemed a private place. The court looked at things like how far he was arrested into his driveway, how far the driveway was from the road, that it was single-family housing, and the opaqueness of the fencing around the property. No bystanders or neighbors watching were noted. The fact that he likely raised aural holy hell to the police officers was deemed unimportant. The police were expected to be able to withstand that sort of behavior.
Had the neighbors or looky-loos been able to see the arrest the court would then have decided how "affected" they would have been. And mention was also made about whether whatever was said by the defendant would have to serve no legitimate purpose (you can imagine one million nasty comments which would not serve a legitimate purpose).
Finally, the court mentioned having to see if the defendant must have created a conscious disregard of a substantial and unjustifiable risk of public nuisance.
While the facts in Gates' arrest seemingly had a few looky-loos, I don't know how far from the street Gates' porch was located, whether the looky-loos could hear what he was saying, and so on. But the case law is pretty clear that police are assumed to be personally pretty caloused to these sort of disruptions. It is the public who they look to see if they are "affected". And if Gates' comments were comment that held a legitimate purpose well, he could scream those questions or comments to the hills, really.
So, this is the way I see it:
1. Was the incident in a private or public place? It was Gates' private residence.
2. If it was private, which it was, was it in a place the public could be affected? Gates was questioned inside his private residence and no public was affected by the questioning that went on inside the house. The officer told Gates to go outside due to the kitchen acoustics and once on the porch when Gates repeated his comment then was arrested!
a) Was Gates' comments while on his porch in a private place? Yes. But by then a crowd had gathered.
b) Was the crowd a crowd of police officers? If so, they are exempt. If there were bystanders then go to #3.
c) Was Gates on his porch of his own accord and volition?
3. The court will look at what the subject said, how far from the street he was, who could have possibly seen it or heard it (other than the police officers) and whether public individuals would be affected by the incident.
So, now what Gates said while on his porch will be scrutined. How far was he standing from the bystanders? What did the bystanders hear him say, if anything? If only the police officers heard his comments then it is exempt. If the bystanders heard Gates' comments like "YOU ARE A RACIST" or something were they personally affected by Gates' comments?
4. They will also look to see if what Gates said held any legitimate purpose (What is your badge number? Who is your supervisor?)
Who is your supervisor= legitimate purpose
What is your badge number = legitimate purpose
What are you arresting me for? = legitimate purpose
You are a racist! = maybe no legitimate purpose
5. Finally, "[n]othing less than conscious disregard of a substantial and unjustifiable risk of public nuisance will suffice for liability."
Ugh. This one would have to be coupled with something like "YOU ARE A RACIST!" yelled at top volume and guaranteed for the public to hear and be affected by.
