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.
