I see that it has been used widely in just one day to justify declarations it was a right-winger action, with no proof but 'reeeeeee'. Under 1% of comments are 'this was a very bad thing' but 50% or more are 'oh, it was Trumpers'. There can't be that many soulless uncaring heartless commenters, so I'm thinking it's campaigning again with bots. Possibly to enable more false flags if Trump proves election fraud and claims office, then there will be bombings in protest and the media will try to pin them on the right.
