Are you really that dense, or are you just playing a rube for sympathy? The goal of the mob was to stop the certification process, so that states could then intervene and appoint tRump, in opposition to what the voters wanted. A couple of Senators voted for exactly that, and the plan was to have Pence refuse to certify. So what if that is illegal? So much has been done over the last 4 years that was blatantly illegal and not prosecuted. They got really close to succeeding.

This is by definition sedition, a clear insurrection against the government.

Wake up. Pay attention.
