Yeah, I hate that whole "due process" thing. Government agents should be empowered to do as they see fit, without fear of any consequences.
Don't get me wrong, if the guy did it, he should be executed. But there should be a proper trial in which the government has to prove its case before abridging an individual's right to life, liberty, or property. Anything else is the mark of a tyranny. How the above posters could support what they do and still call themselves conservatives is beyond me.
You mistake justice with a legal trial. This was rough justice and we can all recognized it. The police officer should be tried since he acted beyond his authority. But still that does not mean he did not enact true justice.
There was a confession and then the ultimate penalty.
Individuals delegate reponsiblity for justice to specialized elements such as police and courts. But still justice is the responsibilty of the people. That is why we cheer this action even if it was illegal.
