I find it hard to blame Clinton for the email thing because she had to go through a lot of hoops to accomplish it.
Any IT undergrad would have implemented the most minimal security policies, even before consulting with their client, Clinton, about taking steps to secure the server. They are at no fault in terms of the legality of Clinton's server but they would responsible for making sure it was secure.
Multiple intelligence agencies sent emails to Clinton. Intelligence agencies. Are you telling me that they had no idea where they were sending classified information? I make sure my checks are going to the right destination in as a secured manner as possible, I at least get a receipt. You're telling me that intelligence agencies had no idea that they were sending to mail to Clinton's private server? Mind you that heads of state are constantly surrounded by security and intelligence personnel. Any electronic device in their possession thoroughly is screened. There is absolutely no way in hell that it wasn't known that Clinton was using a private server and that others had no problem with it before it became a huge news story. And no one sends highly classified data without knowing the end point. To indite Clinton for the emails would be just knicking the tip of the iceberg.
I like how more people are cool with Snowden copying and exposing NSA procedures than Clinton being allowed to store her own emails.
