Luigi Mangione

I don’t see how the ruling class benefits by throwing the wrong guy in jail and letting the killer go free.

Because they can't find the guy that really did it and someone has to burn for this. Executing the wrong man still scares the peasants. Throwing up your hands and saying "we can't find him, guess he got away 🤷" will cause 18 more copycat killings before your press release is finished. Ergo, find someone and pin it on them, no matter what it takes.

If there was a non Luigi killer he would have claimed responsibility by now.

Why would anyone possibly do this when they just successfully got away with their major crime. That's the stupidest thing I've ever heard. The real killer is laying extremely low until their crime is no longer daily national news. Especially because the guy getting pinned for it is being threatened with major terroristic charges and execution, no one is going to pipe up and say "no actually I did it, defame and murder me instead please".

Doubly so when it's becoming increasingly evident that the police are running a clown show that doesn't have a chance in hell of actually convicting. If I didn't know better I'd think they wanted to let Luigi walk. So the real killer is safe and secure in the knowledge that nobody is looking for him anymore and the guy they did catch has an extremely slim chance of facing real consequences.
