a vest reserved for people who are a suicide risk

I haven't seen the picture but.... Straightjacket?

Case closed, no loose ends

This is America. We build whole industries (the insurance industry) around killing people for profit.

To send a message and to look like they solved the crime. They feel confident the real killer will stay hidden or has left the country.

Buddy if you think the system is about "justice" I've go some news for you

When police think they have right suspect they often do everything they can to prove that person did it. Essentially, once they have their targets set on a suspect, they shift from trying to figure out who may have done it to putting all their resources into finding evidence against the suspect and building the strongest case they can against them. This includes ignoring evidence that is counter to their theory and discontinuing investigation of other leads.

Their goal at that point is to convict. Because, to them, getting a conviction is success and the person going free is failure. Alternately, getting the person to “commit suicide” is success because they can claim that they were guilty and no trial is necessary.

It’s all about winning and getting a conviction because conviction=justice=case closed. And that means the public can rest soundly knowing “justice” has been served. Especially after PR has done their work.

Prosecutors are the same. They treat their job as finding anything and everything to get the conviction. Exculpatory evidence is ignored and buried. If “evidence” is planted/manufactured, they do their best to ignore and hide that fact and make said evidence look real. It’s the defense's job to prove innocence. In theory, the police should be working to find and provide evidence for both sides, but the police and Prosecutors anre working toward the same goal, leaving the defense severely hindered.

This is the system that railroads people into conviction. They use the media to amplify their story and make it look like they are infallible. When information comes out that counters the police/prosecutor story, they circle the wagons to protect each other and discredit the information that contradicts them. Because they think that they are the good guys and even if they got something wrong, their original hunch must have been right.

Simple, they want the public to believe that if they follow in the killers footsteps, they will be caught and go through hell in order to dissuade other people who might do the same. There are obviously a lot of people who applaud his actions, so to try to prevent them from getting the idea that they can do this too, they make a show of force to make them think twice.

In the end it doesn't matter if Luigi did it or not. As long as people are scared of the pinishment, they will hesitate to imitate.

Not true justice, but they never really cared about that to begin with.

The wealthy elite want an illusion of consequences for attacking them more than they need actual justice. They didn't want the plebs thinking they can get away with attacking them, or else more will happen.

The Adjustor had 1 target (so far as can be told) and it took almost a WEEK to "catch him", which took a tip in to police to manage

It wouldn't be too out of the question to assume he won't strike again and that any random fall guy is safe from a repeat attack blowing their plan to shit
