The only question now is which junior staffer is going to "admit" to scrubbing the emails before they reached Hillary. That staffer will be in possession of a large Swiss bank account, real soon. Just don't take any late-night walks in the park, pal.
I would imagine that this is not the case. It is near impossible to strip the classifications and not get caught.
Suppose she received an email marked TOP SECRET/SCI/NOFORN. She can say she didn't know it was classified when she got it because there was no classified header. Ok, so who reads her emails besides her, and who would strip the headers before she got the emails? If she names someone who didn't have the proper clearance, she is guilty of allowing someone who didn't have the proper clearance access to classified information. And there is no defense for that. If she says she doesn't know who stripped the emails it's even worse because in her own words, she was so negligent in her job that a total stranger could have read the emails. Checkmate.
