50/50 in my mind.
Like yes police incompetence should be expected, but they broke every rule arresting him, searching his bag, etc etc. Evidence being inadmissible aside, the police did a great job of substantiating our suspicions that Luigi was framed.
On the other hand, this doesn't sound like someone who didn't do it. https://www.youtube.com/shorts/R7R6dmYOVfc
Like maybe he's alluding to the framing being an insult to the american people. But me personally if I was being framed by the government and desperately trying to get help, I would say it more plainly.
