I don’t think mental illness necessarily factors into his being caught.

I do lean towards Luigi Mangione being guilty however the subject of his guilt I think is less important than the public outcry against health insurance companies and their abuses against the American people.

Also if he’s guilty that doesn’t mean we have the whole truth. NYPD especially have a history of interfering with investigations.
