A well written article, thank you for sharing. I think this did a better job of characterizing why people are so frustrated than most things I've seen.
There's been lots of critisisms of how callus the collective response has been, but at it's core, the anger folks have really isn't about worshipping a killer, it's about how humanity seems to belong exclusively to the rich. All while they systematically deprive the poor of their basic human dignity and at times, even lives.
It's well documented that serial killers tend to preferentially go after the homeless, drifters, addicts, sex workers, etc because they know the law gives no shits about them and will probably not even bother to investigate beyond a superficial glance let alone actually prosecute. Those groups are effectively medieval-style outlaws that anyone can kill if they wanted to. You'll even get police flat out saying that investigating their deaths would be "more trouble than it's worth" or "divert resources from more pressing matters." They're literally viewed as subhuman in the eyes of the law.
Jordan Neely is anything but a victim of the system. Neely was a violent criminal who was given chance after chance by the system to reform himself. He was even given a place to stay by the court but he left after a week. As the British would say Neely was a wasteman. Neely had over 40+ arrests and had a long history of violence sure he had a rough childhood and the drug addiction but there are plenty of who have that and don't grow up to menaces to society like Neely.
Daniel Penny was completely in the right and did nothing wrong. Neely was threatening everyone in that train and punched an elderly woman in the face. All Daniel Penny did was what the police should have done. Frankly, the only victims of the system here are the people of New York who had to deal with Neely's reign of Terror.
I feel like Neely is also a victim of the healthcare system or lack there of. I live in the NYC area and there are so many "crazy" people everywhere literally screaming in the streets. These people used to be sent to state run mental facilities that all closed down, now the system just lets them run loose all over the city.
Neely had already been in mental hospital to multiple times in the past not only that he had a strong safety net. You can talk about rehabilitation all day but the thing is the person is supposed to want to be rehabilitated. Neely clearly didn't want that. For whatever reason he was content with being a waste of air.
