How do you abuse your power, but did nothing wrong?

I have to ask this question of how can Palin be found guilty of unlawfully abusing her power as Alaska’s governor by firing her former brother-in-law who was a state trooper. This is a from a ethics committee (Bipartisan , both Dems and GOP) investigation.. She did nothing wrong in firing him, but the procedure that she used to lead up to the firing was a direct violation of an abuse of power. I find it quite unique that Limbaugh and Hannity have refused to mention anything about her abuse of power! Being impartial does not count against these guys... So when will we find out what she actually did wrong?
