If a jury saw this as documentary evidence entered into the court record, I suspect it would be enough “proof” for most of them. Although with today’s quality of jury pool, perhaps not.
Interesting that you mention that.
When one gives a taped deposition or testimony at a jury trial, one of the first things they tell you to do is not to touch your face. It creates bad optics, can be confused with something disgusting, and generally just looks bad. They instruct you not to do it even if you have the misfortune of sitting at a defendant’s table.
Hillary of all people would know this.
These were signals for sure. However, if Trump makes a big deal about this the ever compliant media will make him out to look like a nutter.
Given the favorable reception to his performance, it’s probable best to drop a vague hint that he knows what’s going on. He needs to keep a little tube of Sarna anti-itch lotion and offer it to Hillary if she pulls this crap again.
And if he’s a master negotiator, he should haul the future moderators into his office and put the fear of God into them if they try this again.
