I know many don't want to hear it, but this is what you get for "moving forward" and not punishing government-approved torture and for not setting a standard for the future that it's not acceptable.
Sadly, even if Trump's administration does far worse crimes than Bush's administration did, there probably won't be many Democratic nominees, if any, that would commit to putting people in prison over those crimes, once in office. They'll "move forward" once again, so they "don't rock the boat", and "unite the country". So no lessons will be learned - again.
