They staged an uprising against the federal government. That’s the dictionary definition of insurrection.
Threatening government officials would be a separate crime. Anyone who did that on 1/6 needs charged and will be. Attempted assassination is another, much more serious crime. But to my knowledge that didn’t happen on 1/6.
See, this is the problem when the hype gets ahead of the law. Prosecutors are bound by the US Code. They can’t charge people with ‘insurrection’ just because the word is being used by partisan pundits. Actually, I think sedition would be the actual charge.
Have we seen that indictment yet?
