To convince the public he’s guilty. It’s one of the ways they skew the narrative.
Remember in the movie “SWAT” where that monster guy who entered the country illegal to kill the one guy and then offered money to get him out? That’s Hollywood doing their part to put the idea in our minds that this kind of thing is warranted.
People do want to help Luigi and that scares the shit out of them too. They expected people’s moral compass to make them side with the CEO he shot. But that’s not what happened. The general public is very much pro Luigi.
The people leading the push for his prosecution are very much out of touch with that reality though. Cops and prosecutors have some of the best healthcare in the country.
