You're telling me that the Secretary of State (with 20 some years of government experience) and her staff didn't know enough about how to handle sensitive and classified information to avoid the risk of it being compromised. If that's true, then Clinton is incompetent.
That aside, whether she knowingly mishandled classified information or not should have been sorted out in the judicial system after she was indicted and charged. However, Clinton is a privileged person and now she has confirmation of just how privileged she is. She'll be putting arms and legs over the legal line knowing that she'll never be called out for it and even if she is, nothing will come of it.
I understand that no amount of the truth will sway a dedicated Hillary-lover (H-l) from his/her determination that HRC is not a crook, not the devil, not evil, not corrupt, not a serial murderer, not a conniving fiend; and that's the least of their delusions!
