If it was incompetence, then that's not proof.
A third is they simply don't care enough to publish the retraction. They got the hits, cynically-speaking. In legal terms, they're more than likely covered because of the sheer quantity of unknowns about the man's death (that are still unknown). And this again, is not proof of malice.
So, again, you have no proof. You have a preferred theory that matches up with your presupposed conclusions, conclusions that Greenwald's latest screed aligns with. There's nothing more to it than that. There is no proof, as much as you try to claim otherwise. This entire tangent (much like a lot of the OP in general, really), is laughable in its attempts to uncover truth in journalism.
I think Greenwald, who knows the environment of the NY media as an insider, was early in seeing how willing it was to distort news to favour one side. So he sees that as an evil, and only the other side (in the current two-sides very divided US) allows in some media time within the US. That does not mean he is working for them. It means that the truth in this case happens to be favorable to this side and the situation is so rotten that it only gets published there.
Incompetence is possible but I just can't believe it: the NYT jumped into pushing that narrative, and stuck to it a long time, because it advanced its preferred views. Not correcting it quickly can only have been deliberate.
I see no reason to doubt that NYT reported the fire extinguisher story in good faith. From what I can understand, they corrected it after the police finally said Sicknick suffered no blunt force trauma. Also, there still appears to be no definitive version about what happened to him, so it's not like they were suppressing some game-changing facts.

And in the grand scheme of things, these come across as rather minor details :shrug:
They corrected it only long after the police denied the early report. That that early report got around.
But more importantly, these things were not small details. They fed and keep feeding the current divisions, pushing people into thinking about more political violence. As
@Farm Boy noted, those who heard about it then and unlikely to have heard about the correction. And this is a known situation with the kind of false reporting that was done. It's not an innocent mistake, professionals know this (the early false reporting "sticking") is a thing. For one example even tonight I was reading some
guy's blog on history, not expecting anything on current politics there, and look at what I found, search for the post in January 11:
That mob then broke into the Capitol building. A matter of seconds, bought by a single Capitol Police officer holding off large numbers of intruders by himself, separated the mob from seizing senators and representatives en masse. In the course of their assault, the mob bludgeoned a police officer to death with a fire extinguisher and ransacked the building. One member of the crowd was shot and killed. Several others died and dozens were injured, including police charged with suppressing the riot. It was a violent insurrection, an act of political violence.
This guy probably made up his mind on calling it "an insurrection" because he heard of one dead by the mob. But that was a lie he had been told. The lie, and the conclusion, stands uncorrected and nu-reevaluated that blog. This is the
New Your Times' doing. Reading it led me to revisit this thread and reply, though indeed I don't expect it to make much good.
