To clarify: There are only two actual reasons that you can legally be held without bail. The first reason is that you’re considered a flight risk. The second reason is that you’re considered a danger to yourself or others if let out of prison before your trial.

For the first reason, this basically means that the courts don’t believe you would return for your trial, and would flee instead. Maybe you’re rich enough that you can afford to lose the bail money. Maybe you have international connections and can disappear to another country. Maybe you just have a history of fleeing. The Adjuster is 100% without a doubt a flight risk. He fled authorities and evaded a nationwide manhunt for an entire week. And since Luigi is accused of being The Adjuster, he is considered a flight risk.

For the second reason, this is basically the court going “you were accused of something so violent or egregious that we don’t trust you to avoid doing something similar again while out on bail.” This is most often used with cases like school shooters, serial killers, serial rapists, serial burglars, domestic abusers where the victim could be targeted again, etc… But a scummy pro-corporation judge could construe The Adjuster as a violent offender who is likely to strike again.
