13 Russians

I guess we will just have to wait and see what it all means.  Robert Mueller has indicted 13 Russians for meddling in the U.S. presidential election in 2016.  But what does this mean?
If they were actually working for the Russian government, it might be worth making a diplomatic protest over, but unless the ‘interference’ actually  involved hacking voting machines, distributing false ballots, or arranging the closure of polling places in key districts, then it’s probably not illegal.
See, a Russian person, even one who is kind of sleazy and uses a fake name for their account, has a right to have an opinion on American elections.  I’m an American citizen, and I have posted my opinion on elections in Britain, and Ukraine, and Italy, and France, and of course the Czech Republic where I live.  Frequently.  If they had looked for accounts with a negative view of Hillary coming from Brazil, or England, or Nigeria, I’m sure they could have found plenty.  She’s been on the world stage for a long time and you’d be hard pressed to find a country where at least some people haven’t formed an opinion of Hillary Clinton, and it’s likely that 50% of those opinions are negative.
If they prove that these people are working directly for the Russian government, well, that’s objectionable, but is  it any  worse  than our U.S. politicians constantly  making snide remarks about Venezuela, or actually invading Syria and arming terrorist groups to try and  oust their president?
I hope this keeps going up and up until it touches somebody that counts, but I would have preferred they go after Trump for tax evasion, or  money  laundering, or corruption, or anything that is actually, clearly and unarguably criminal. I wish Robert Mueller all  the  luck in the world, and would love to see him bring Trump down.  However, I don’t think that charges against ’13 Russians’ is going to do it.
