Even though I detect some sarcasm, this is the best argument for Palin ... that Monegan served at the pleasure of the governor, and thus she had the right to fire him. Actually, she fired him and then offered him another job. The ethics investigation came about because of concerns (thanks to some tape recordings) that she fired public safety commissioner Walt Monegan because he did not ensure the firing of her former brother-in-law.
I didn't say tazing him wasn't wrong, I was just trying to "flesh out"

the incident a bit.
You also seem to have the facts mixed up a bit. The trooper was not fired. Palin did not fire him and does not have the power to do so. Her office -- and there are recordings of this -- was putting pressure on public safety commissioner Walt Monegan to fire the trooper. When the trooper (who had already been investigated and disciplined) was not fired, Palin fired Monegan. The ethics investigation was launched because of suspicions that Palin fired him because he did not fire the trooper, her ex brother-in-law.
Palin promised to cooperate fully, and said she had done nothing wrong. Alaskans seemed to accept what she said for the most part.
I was kind of meh on the whole Troopergate thing, until the McCain campaign took it over, and started messing with the process. They don't want the results to come out right before the election, period, because the results may look bad. So the McCain camp has parachuted into town and are, among other things, smearing Monegan and French, who are LOVED and respected up there.
Here's an editorial from the Anchorage paper that has some more information:
