Next time there's an industrial accident where negligence is determined, or next time a drunk driver kills or injures someone, they can use what will be known from this point forward as the Clinton/Comey defense. Yes they were reckless. Yes they were negligent. Yes laws were broken. However there was no premeditated intent, so there will be no charges. Yep, that'll happen.
As far as we know Hillary's emails hasn't killed anyone.
