How could the Marines catch Zoro? The first time Luffy met Zoro, Zoro got caught by the Marines because he killed Helmeppo's pet wolf.



He was already strong at that time, he could easily defeat Morgan, a Marine Captain there. Had he deliberately made himself get caught? Why did he do that?
I think nothing is mentioned in the manga about this. According to the anime (second episode), Zoro was blackmailed by Helmeppo to surrender for 1 month otherwise he will ask his father to execute the family. Zoro agrees on the condition that the family will not be harmed.
