When I say "people" I mean "people," I don't know how to make it clearer than that. People in the administration. People in this thread. People in concerned about justice issues. People.
The judicial system is designed to examine the 'real truth.' It includes appeals processes in case the system got it wrong the first time. And there's always the Supreme Court.
I'm ambivalent about the President's ability to grant pardons and commute sentences. I think it runs counter to the separation of powers and checks and balances in our form of government, but since it's a power specifically granted to the President, I'm OK with it.
The relatively high number of commutations and pardons by President Obama to me smacked of racial pandering more than it did of righting a legitimate wrong.
