> The brought a mock up of a gallows -the same kind other protesters bring to anti-Trump rallies.
I'm not aware of this being a widespread practice at anti-Trump rallies.
> Do they need to subpoena ~400 lawmakers and $10 donors to the campaign? I think it’s obvious that that is overreach and intimidation.
Well... it's not unlikely that there might have been "inside help" from lawmakers and/or their staff or even general Congressional staff. The purpose of an investigation is to go, dig deep and fully take apart whatever conspiracy there was.
As for the donors - anti-terrorist laws in pretty much every country don't care if it was just a $10 donation. Donate to a cause that ends up being terrorists, be labeled as a terrorism supporter.
Rioting is not terrorism. Terrorism usually involves conspiracy and planning they're typically not one-time, ad-hoc events. I know governments all over the world like to go overboard with that terms since Sep 11 because it's a get-them for free kind of card, but to me it means actual infliction of terror. A mock gallows is not. If it were, lots of protests with burning effigies, etc. could quite possibly be considered terroristic events.
the gallows mockup was one of the reasons for the reaction to the Jan 6th stuff.[0] , although as far as what political party the owning group is using it for or against is sort of up for grabs.
