So if someone emailed Pence and said they would stab him if he certified the election would that be an insurrection? They are attempting to influence him to change the result of the election.
Surely the level of organization and possibility of success need to be taken into consideration? Otherwise every moron with a social media account or a sign could be guilty of insurrection.
A single bot did not email him. They went 1000 strong in person, were armed, and people died.
