Lol you have no idea how clueless most old lawyers are about technology.
People are assuming that Hillary went into this thing blind and left to her own devices.
"I'm old and nobody told me what to do, so I'll just set up a private server and use my regular email like I always do."
That would be fine, if it weren't for the fact that she was warned against this very practice (on multiple occasions). Considering the fact that technology was becoming a lot more beneficial and utilized a lot more often (in life in general), the State Department revised their own rules and procedures regarding the use of technology in the work place.
-Do this. Don't do this.
So blaming it on "old age" just doesn't fly, especially if you were already warned to stop doing something (and especially if the warning was sent under your name).
