I just did, again.
Do you actually read anything I post?
It puts the lie to his "I didn't know" defense when he actually posts it. I ask again, if he didn't understand the meaning of something he found "interesting," why did he feel the need to post it?
Otherwise, the picture is just an innocuous collection of rocks, conveniently arranged in a random assemblage of numbers.
You couldn't possibly expect any prospective grand juror that he didn't know what it meant at the time he posted it.
The Miranda Warning puts it succinctly:
"You have the right to remain silent, anything you say or do can be used against you in the court of law."
Both the "say" and "do" elements have already been met here, as well.
Comey is toast. Sorry, kid.
