So they didn't even attempt to enter the building and they certainly didn't attempt to overthrow election results? I just cant see how you think these are the same category of event with respect to political impact.
They burned the church and tried to break into the White House forcing an evacuation of the president! The 1/6 riot, by contrast, was by turns both violent and civil, but no one was armed and attempting "to overthrow the election results". In fact the Trump plan of continuous debate over the merits of the election was thwarted by the riot. It was diametrically opposed to his interests and ended up favoring the Democrats. Many questions still linger over the identities of major participants, including the "pipe bomber" and the "scaffold commander", whom the FBI unaccountably never identified. Note that the 1/6 participants were relentlessly tracked by the state for years by some 6000 FBI agents and tried in DC courts, unlike the 2020 rioters aiming to storm the White House.
