Lawful Stupid/Playing With

Basic Trope: A Lawful character carries the Idiot Ball because that is the Lawful thing to do

Straight: Jason, a self-declared Knight in Shining Armor, tends to go a bit overboard when it comes to enforcing the law, to the point where it supersedes other considerations like common sense.
Exaggerated: Jason the paladin insists that he is a paragon of saintly virtue out to purify the hopelessly corrupt world and overreacts to anything he deems sinful, to the point of dragging people to jail for jaywalking.
Justified: Jason is a naive idiot.
Inverted: Chaotic Stupid
Subverted: While Jason is a stickler for rules, he isn't so stringent about enforcing them that he loses sight of common sense.
- Alternatively, he is Lawful Evil.
Double Subverted: After seeing his allies snatch a purse, Jason catches them and calmly makes them return the money and apologize, and seems to empathize with their plight and let him go... but then clubs them upside the back of the head when they turns to leave and drags their bleeding bodies to jail.
Parodied: Jason realizes that he is jaywalking in the middle of the forest, and promptly pulls his sword to kill himself in a holy fire of justice.
Deconstructed: The Knight Templar, which presents zealousness at the price of compassion as a villainous trait.
Reconstructed: As a result of something he did, something bad happens, causing Jason to have a My God, What Have I Done? moment. He learns that having common sense is important, and stops being Lawful Stupid.
Zig Zagged: Mason starts out as a Reasonable Authority Figure, though he has a few niggling issues that act as his berserk buttons. These are decently explained, however, and he's shown to be aware that these cloud his judgment and relies on others to keep him from losing sight of his common sense. Unfortunately, his protegee Jason is a full-fledged Knight Templar, and while Mason is able to curtail Jason's Lawful Stupidity for a time, he ends up succumbing to the Mentor Occupational Hazard, after which Jason takes over the organization. Naturally, it gets worse.
Averted: Jason is a Lawful paladin that has common sense.
Enforced: "We need a rival for our Loveable Rogue to butt heads with! Let's make a paladin with little common sense"
Lampshaded: A Street Urchin caught stealing bread sarcastically asks Jason upon being caught if he's gonna torture him for such a small crime.
Invoked: ...Which is exactly what Jason ends up doing to the Street Urchin.
Defied: The player behind Jason is an experienced Dungeons & Dragons player, and knows how to be Lawful properly.
- Alternately, Jason became a paladin because he was sick of Lawful Stupid paladins, and wanted to show them how they should be acting.
- Jason yells "Screw the Rules, I'm Doing What's Right!" when he encounters a choice between breaking the law to save hundreds or following the law and letting them die.
Discussed: "Jason is a real stickler for the rules! Why can't he just have any common sense?"
Conversed: "But his actions are morally questionable, as he doesn't seem to know how to be lawful without being unintelligent!"
Played For Laughs: Jason knows damn well how many times he has exceeded the speed limit, gotten a parking ticket or jaywalked or done any kind of minor violation of the law in the book, but he is still determined to punish himself despite being told by everyone he knows that he should really just relax.
Played For Drama: After the urchin grows up, he proceeds to frame everyone Jason loves and respects for equally small crimes, and making Jason aware of it so he's forced to torture them too. After Jason is left alone and confused, the urchin plays one final head game on Jason by crafting a scenario with such a terrible Logic Bomb that Jason is finally forced to make a Zeroth Law Rebellion or go insane. Once he's finally free of his Lawful Stupid way of thinking, the urchin wraps up the Tragedy by revealing the manipulation, and how he could have saved all his friends if he'd just been willing to use his brain.
They Plotted A Perfectly Good Waste: The president performs an unconstitutional act in order to save the country from being brought down by a Dystopian Edict, with Jason as the only witness. The president explains that due to constitutional technicalities, reporting it would result in the dissolution of the government and cause public chaos, Jason reports it anyway. As the system crumbles and the country becomes a lawless hell, Jason slowly wonders how he can uphold the law if there isn't one to uphold.
