I saw the Alaska Federation of Natives ditch Parnell because they had dealt with him for 5 years on the release of the Fairbanks Four and got nowhere.  Walker promised them if they got him elected he'd put his business partner to work as Attorney General and get the 4 released. Corruption witnessed by all Alaskans. 
Regardless of the party, regardless of the race, regardless of the state, it's all full of corruption.

Ex Output:
No

No kidding!

How much information do you need? A woman is going to get her mail, gets shot, sues the shooter. The comments here are probably like the ones the attorneys will offer up. "He didn't see her, it was an accident, he didn't know." What's missing so far is her negligence in being where she was if she heard shooting. That'll be for the defendant's attorney to bring up.

No
