Daniel Penny 12-2 Closing Arguments begin in trial of veteran

Not on board with how they're framing this and the cause of death. He died because the blood was cut off to his brain. But he wasn't just loud and crazy, from what I heard, he broke some woman's jaw, ok? He was a threat to the passengers and the police/DA just enable it. But how long did Penny hold the pressure? Apparently 5 minutes. I think that if the police were telling the truth about holding the pressure for a full minute after the guy went limp, then that would in fact be manslaughter. But it sounds like the police/DA made it up. Bystander footage shows his estimate was accurate, 5m total not 6, not the police estimate. So there'd have to be some evidence of Penny doing that, not just the police saying so, who weren't even there, or quoting some guy in the subway car. And in that case, would it be negligent homicide, and can you even justify that charge? I don't understand the difference between that and manslaughter, and I don't understand how it can be homicide if it's manslaughter. He was a corporal who did MCMAP, he isn't some master martial artist, so manslaughter sounds to me like the most you could reasonably charge him and if you get a conviction, are you putting people in a position where the police aren't defending them against subway violence, and they're not allowed to defend themselves either?
This is the new footage from the trial with trial details Nov.4 from Murdoch's paper-

It seems to contradict the DA's 6m timeline. SO I think for either charge, the case hinges in whether Penny was negligent. The media is obviously politicizing it and the criminally negligent charge on top of manslaughter tells me Bragg (DA) is too. Are they pre-determined to convict him for political reasons or is this a real trial, that I don't know.
