I understand the reasoning behind burning the cabin. They didn't have to risk anymore officers lives in trying to eliminate him through breaching and entering. Tactically it was a smart decision. That being said it was completely, utterly, irrevocably, wrong. It should never have been done and is a violation of many laws. They should have used their power that fell within the law to either kill him or apprehend him. Either way I'm glad he's dead. Though his cause of wanting to bring to light the corruption of the LAPD was noble the minute he stooped to killing he became as bad as those who sought to unmask to the world.
