Now, we are where it makes sense to have discussions because most of it is known. So the Russians (still out is if it was the government, private individuals working for the government, or individuals that just wanted to demonstrate how stupid politicians are with their electronic equipment) hacked into and learned a bunch about the Clinton camp and made some of the stupidity public.
There are people (not me) that praised Assange and team for nearly the same thing if it was embarrassing GW Bush and Republicans or declared Manning a hero for embarrassing America (could it have tilted the 2008 election to Obie?). So electronic espionage needs to be investigated. I'm not sure you're ever going to find the individuals responsible or determine if it was on behalf of or at the behest of Putin and the Kremlin.
But let's look at what we actually do to people that are caught that ARE citizens? We let them run for President, we pay for their sex change and release them decades before they were due to be released, as long as they hurt our "enemies" what they do is okay because they are doing a service or demonstrating the foolishness of the individuals, companies, or agencies..... Look at the press and their coverage of candidates, they get to pick their winners and actively slant stories and commentary to help them get elected, and we celebrate the "freedom" of the press.
The Russians hacked into our political parties and candidates and actively embarrassed one of the candidates (who happened to lose). Other than the fact that they are a foreign power, is it really much different than what our own press has been doing for the last 25 years or so? Our political process HAS been hijacked, but it happened long before the 2016 election cycle, what do we do to get the press to be fair and balanced in their coverage? If a foreign power DOES try to actively change an election's outcome, what can we do about it?
