Whatever. [Marco doesn't actually have a problem with killing random police. This is Marco here.]

Wait until I get Ace to take on the police? I will always approve of dicking with them, but even without his devil fruit, Freckles is something of a genius at arson and mayhem, and I'm sure he'll want to hit them up too.

You planning to just go straight from the precinct to breaking loose the trolls? [Marco knows what police are. They're just the localized versions of law enforcement country to country and thus even less equipped at dealing with pirates.]
