[DC] How the heck do Green Lanterns patrol entire sectors of the Universe?!

So, Hal Jordan gets a magic ring of green goodness, and suddenly he's a space-cop who can hit people with magic, green chairs right - but how on earth is it plausible for him to patrol such a large area of space, especially when the distance between habitated planets is huge. And what constitutes a problem that requires a Green Lantern? Is a common mugging something that will pull Hal back to Earth from ages away, or is he content to let Earth police/superheroes deal with it - and if so, what's the point of the Lanterns - or how do they function at all?

No, of course, he won't come back to Earth for a common mugging. Don't be silly. The Green Lantern Corps focuses primarily on interstellar conflict, especially in cases where civilizations that have not achieved significant space travel capabilities are threatened by those that do. Given that, the responsibilities of the Green Lantern are narrowed down considerably to patrolling those worlds that can move through space, which are relatively few in number. This facilitates ease of planning patrol routes, using the superior technology of the Lantern ring. Of course, Lanterns are also given individual liberty in the performances of their duties and are not necessarily beholden to only preventing one sort of offense or another; their overarching mission is simply to preserve the integrity of peace and life in the universe.
