But I can say that something like this isn't too surprising, assuming you hired a lawyer with a brain in his/her head. They really like the idea of deleting evidence that could be used against you in a court of law, if they're hired to work FOR you.
This is why businesses are being pushed to start purging all of their employee's email on a regular basis. They want to preserve that plausible deniability and ensure some former employee didn't say something in a company email you weren't aware of that winds up costing you $'s in a lawsuit.
If this is an attempt to discuss if Clinton is guilty of anything or not with running her own private mail server? I think the answer to that is really pretty obvious.... Yes, of course she is. If any of us worked for an employer who provided us with a company email system for use with company-related things and we just decided to conduct business via our personal Gmail accounts, or some home-brew Linux server? How long do you think we'd stay employed there once that was realized? In a case like hers, it's only magnified as a problem because we KNOW she was allowed to handle classified content in her mail. So the hunt is on to prove she actually possessed some of that on this unofficial server. And if her lawyers did their jobs properly, there won't be much concrete proof that she did so, or at least that she ever accessed it once it was sent out. That doesn't make her less guilty though
