I think Hillary knew whatever was necessary to make money off her emails. If that meant allowing the Chinese to read them, I would believe that she did that.
For an ignorant, incompetent woman she seems to have accumulated quite a bit of wealth. Perhaps there is an explanation other than just having good luck.
Hillary was doing her best to suppress her unethical and criminal activities. Hillary was probably still smarting from her experiences with the Whitewater investigation. Remember the missing billing records which magically reappeared once teh statute of limitations expired.
