Virginia and Maryland were on the brink of invading DC (had the government continued to resist deploying the National Guard and the riot got even more out of hand) with all the bizarre consequences of that…

To be fair it’s not like the mob was that determined and capable to actually murder Pence etc. (at least there weren’t any clear signs of it). They scattered immediately after the first guns were fired (I mean those close enough to witness it). So more people might have died but it would have primarily been the rioters rather than anyone else..
