Added point for any campaign: the opening situation/encounter should further the story of the campaign. If the PC's don't want anything to do with being outlaws, or at least outlaws in this area, but rather see themselves as this village's heroes, well, this would be a problem of course.
Exactly, how, for example, would one reconcile playing a paladin in this situation. I mean, you bought or were given the map, and as long as the treasure is in some cave that isn't against the laws of good to take, your first option when confronted by guards would be "oh yes we have the map, here you can have it."
Maybe the guard decided to attack them all anyway after you handed over the map, I suppose a paladin could be reasonably believed to decided to defend your comrades against the corrupt guard.
And I suppose letting them out of jail and clearing their names would be a sound enough offer to avoid the "why should we help you" scenario after being imprisoned.
In any case, even if the OP isn't mean, it makes all of this feel much more complicated than necessary.
