The general population of honest people does not have first hand experience with fraud or criminal activity (or what to do about it when it happens in the moment).
They do not understand that some of the sweetest and pleasant people do indeed engage in very bad things sometimes right in front of your eyes.
So many believe a "bad guy" will be dressed in black and be cruel in demeanor.
They also believe anything fake will scream "fake fake fake" when they see it.
They don't understand what to look for or what to do once they see it.
From the videos, does anyone see if they left any suitcases under the table or left any of the votes UNCOUNTED? This would further prove they'd only add as many fake votes as they needed.
