Firstly, Luigi Mangione is presumed innocent until proven guilty.
Secondly, there's a fair amount of real evidence that Luigi is being set up as a scapegoat by the NYPD—a police department with a known history of planted evidence.
Second part: I’m not buying that for a moment. It’s way easier for me to believe that an individual working alone, screwed over by a megacorp who earns more based on how many people they can deny healthcare to, had enough and went vigilante. Vigilanteism and cold blooded murder are not OK, but it’s pretty easy to link cause and effect there. That’s vastly more likely than a shadow conspiracy that’s managed to keep its mouth shut so far.
This does not contradict what I said.
I make no claims about just who or what the actual shooter was. I merely claim that it almost certainly wasn't Luigi Mangione.
