One thing we can be absolutely certain of: Such crimes will never be prosecuted by the current, or a future, DOJ.
Only The People will ever have a chance at that prosecution.
Actually, I've been kicking the idea of a Presidential run myself — I cannot simply sit by and tolerate the amount of corruption (and lawlessness) in the government… if that meant pushing prosecution of those crimes, then so be it. Government agents should be crap-their-pants scared of acting contrary to the Constitution, and I'd intend to make it so.
