A few things: --"outlaw" isn't the best swap for "criminal." An outlaw is not merely anyone who breaks the law; they're someone who's no longer shielded by the law, so other folks can do to them as they like. A more fitting word would be "lawbreaker." --Most of the time, a lockup is a small-time stead for the lawless, what's called a "jail" in America. A full-time stead would be called a "slammer."
