Except, of course, that's not what happened. They archived the work-related emails in December 2014, well before a subpoena, and she instructed the management company that she did not need to keep emails on the server beyond 60 days. The technician responsible for this failed to change the retention policy and at some point late in March, acted on his own to delete the emails.

But again, here is a case where you have accused and convicted someone because you hate her, not because you know the evidence or care. The people who rely on to think for you are telling you that Hillary herself saw a subpoena, got out her trusty jug o' bleach, and started to personally cover up whatever right-wing jizz fantasy conspiracy that they're pretending she's hiding. You see, the thing is, prosecutors generally don't bring charges based on anything other than the probability of being able to get a conviction, and while the narrative Trump and his Breitbart/Sputnik media sources are parroting would actually have led to that, the simple fact is that based on the evidence the FBI has, there is no reasonable probability of getting a conviction or probably even an indictment based on the facts.
Now, the thing is, if you would just focus on the fact that she was very irresponsible in how she handled her emails, I'd buy it. But that's never good enough - you have a hard-on for having her incarcerated and many other people who are in your cult think she should be shot, because they're being lied to and since it fits the hatred that's been bred in them for decades, they accept it without question. I wish I could say that you were better than that, and maybe you'll surprise me and read the report I linked and have the intellectual decency to recognize that if you change the name in the article to Trump, Bush, Rice, Powell, or Brutus the Buckeye, in every single case no charges would be filed and in every case I would agree with that and say the person was irresponsible for doing that.
