Re: Due diligence
"The state of Iowa" can't just grant permission to break into anything they like, just because it happens to be in Iowa. If I were an Iowan householder (read: voter), I'd want to be very clear about that.
In this case, it seems pretty clear that the sheriff's real target is the state-level officials who authorised the test. If he can establish that the guys who did the breaking-in were doing something illegal, then it follows that the people who commissioned them to do it were, at the very least, accessories to that. I don't know what local politics are in play, but I'm pretty sure that's the goal here.
