So to copy this doesn't someone have to to have top security clearance?
How many people have it and wouldn't the system record the breach, time, place, possibly who?
As someone else pointed out, the copy may not have been electronic. Copying from a system rated to handle secret level or above to removable media always involves automated audit trails, paperwork, authorizations, reviews, etc. However, as another poster noted, someone could make note of pertinent details and then paraphrase the information in a non-secure system. This is an intentional violation. There is no "talking around" or obfuscating classified.
That may be one way Clinton is trying to skate out of this: by claiming that she personally never copied classified to her system. BS. Doesn't fly. Two problems with that for the Clinton criminal enterprise.
One, there are security classification guidelines that outline what kinds of information is considered classified. Anyone working with a program is given access to the guidelines and expected to familiarize themselves with it. For example, if you were working with submarine designs, maintenance, etc. the guidelines would probably admonish you that performance specifications (eg. top speed, maximum depth, endurance, etc.) are classified. You don't have to know the actual numbers to know that if you see this data, marked or not it should be considered classified. Clinton and her staff should have known better. Ignorance of the SCG is no excuse.
Two, if anything, such a tactic (claiming she didn't know and it wasn't marked) would merely make her that much more unfit to be Commander in Chief. The Sec. State, Commander in Chief, and a relatively few others in government service have what is called "original classification authority." That is, they are entrusted to have the good judgement to look at information, any information, and deem it classified. Everyone else has "derivative classification authority." They mark/handle information as classified because it came from a source that marked it as classified, or it meets the criteria in the SCG. Clinton claiming she didn't know is an admission she lacks the good judgement to know what is classified or not. Such an admission should be an immediate disqualification from any further consideration for a position of trust - ie. President.
