Downplayed: Only very severe offenses are considered crimes in the first place (as opposed to perfectly legal personal conflicts). Thus while harsh it isn't utterly insane.
President Justice is a Knight Templar who believes the best way to get rid of crime is to instill harsh penalties for even the smallest crimes.
Only one kind of crime ever takes place in the city, thus only one punishment is needed.
Inverted: The President has a ridiculously tiered system of crimes, with varying punishments down to the amount of minutes spent in prison depending on the crime. ("You robbed a jewellery store? 12 years, 6 months, 15 days, 18 hours, and 29 minutes in prison. Oh wait, you injured the shopkeeper? ...I'm adding 6 hours and 30 minutes to your sentence.")
Subverted: One crime is treated as much worse than another.
Double Subverted: That's because they were wildly varying types of crime (like comparing jaywalking to mass murder). Most crimes are treated as equal.
Parodied: All crimes are equal and merit the same punishment...except for one minor crime like staying out too late, which is treated as much, much more heinous than the rest.
Zig Zagged: The crime system generally prosecutes all crimes equally, but fairly. However, many vigilantes offer substantial bribes to judges to add longer and more drastic sentencing to crimes. Corrupt judges also add weight to certain crimes over others, but generally justice is equally served.
Averted: The crimes are treated as different.
Enforced: "The best we can show how evil the system is is to make them kill everyone, regardless of the crime."
Lampshaded: "Well, let's see here - you're not wearing your seatbelt, so that's 30 years in prison. That kid isn't in a carseat - 30 years in prison. And you just shot someone? 30 years in prison."
Invoked: President Justice runs on a staunch anti-crime platform.
Exploited: The president's top advisor, a Magnificent Bastard who's gunning for his job, suggests that he implement an ultra-harsh justice system so he can swoop in and take over when the inevitable backlash hits.
Defied: "While I am concerned about crime, giving harsh punishments to every lawbreaker might be a bit much."
Discussed: "Oh come on! I jaywalked once! Why are you executing me for it? All crimes are not equal!
Conversed: "Wait, why's Stephen in jail this episode? ...He jaywalked? But that's a maximum security prison! And his fellow inmates are all murderers? Ridiculous!"
Since the criminals know that they're going to be facing the same punishment no matter what the crime, they go on a rampage, killing, raping, and looting as they see fit. President Justice just shrugs it off as a side effect of the system, which eventually leads to a massive riot, with massive loss of life for both sides.
The insanely harsh justice system leads to a massive amount of prison overcrowding.
...However, this leads to a takeover by a successor who institutes a more far and just system. Consisting of two tiers!
All crimes are created equal, but good behavior allows you to run the prison.
