RE: 'forbidden material in an online chain' ...
What Hillary was guilty of is adding a comment to a bit of material that in one case wasn't classified until after it was contained in an email chain. In others, the classified material was added by others in the email chain which mean anyone replying to the message after the forbidden material was added was guilty if they forwarded all the earlier comments (including the one with forbidden material.)
One time someone posted a pornographic image on pcom. Others, showing their disgust and shock, replied to original offending post therefore reposting the offending material. I bulleted all the 'offenders' knowing that those 'just replying' had not thought about what their replies had meant (copying of the forbidden material).
Doing so was a grossly careless act and I think the reading is that of some 50,000 emails in the account, only 100 in 13 chains or so had some issues.
Anyone with an IQ greater than 80, if presented with the facts, would understand that the bruhaha involving Hillary Clinton's emails was a gross exaggeration of the whole issue.
Yet while you complain about that splinter in the 'dems' eyes you ignore the log in DJT's eye talking to anyone and everyone on his insecure cell phone nightly since his inauguration over the objections of the intelligence community which knows the Russians and Chinese are listening.
You need to open your eyes because the behaviors being uncovered regarding this regime are not troubling; they are provably criminal.
This all begs the question of whether you want to live in a country ruled by the rule of law or ruled by the hand of those who proclaim themselves above the law.
