Summary
Luffy yells again, without words, and swings his fist back like he’s getting ready for a charge. He freezes as soon as a sword appears at Ace’s chest.
“You will stop fighting now, or your favorite will pay the price.”
Ace can see the realization hit his little brother in real time. It’s the moment the marines caught them back home all over again, but worse, because this time he can see the look on Luffy’s face, the twisted up emotion-
-the way his arm slowly lowers.

Garp taught Luffy how to be a marine and uses that knowledge to break into a government facility by Dezace
Fandoms: One Piece

Summary
Garp wanted Luffy and Ace to be Marines, so he taught them what a good marine should know and how to do it. While Ace and Luffy obviously didn't become marines, that knowledge was, literally, pounded into their heads. With Ace captured and set for execution, Luffy uses that knowledge to bust his brother out of prison.
Or: Why Garp shouldn't have taught an upcoming rookie what Marine codes meant because all it led to was the chaos a pirate could use it for.
