No one should assume that Trump will recede into history on January 20. For the next few years, governors, district attorneys, and police should expect the worst if Trump tries to lead a rally in their jurisdiction, given the potential for violence and escalation. Mainstream Republicans, be warned: This is not your base. Failure to assess the real threat posed by MAGA is what led to the Capitol insurrection, and those seeking to keep Trump in office illegally should not be afforded another opportunity to innovate.

The failure of the Capitol Police and other agencies to anticipate last week’s events also highlights law enforcement’s failure to innovate in countering white-supremacist and violent extremists. These groups organize on open platforms that have little operational security. They brag endlessly about their plans, their guns, and whom they will murder. If journalists, internet archivists, anti-racism activists, academic researchers, and even Amazon’s cloud-services unit are able to identify neo-Nazis posting online, what is preventing law enforcement from doing the same? This is not a rhetorical question—especially given evidence of some officers’ lenient treatment of Capitol rioters…

The scale of the account and content removals on major platforms has thwarted the most-extreme MAGA supporters’ ability to rally one another. However, platforms’ enforcement measures have lacked consistency in the recent past, even as MAGA factions grew more violent. In the coming months, disinformation will remain everybody’s problem. Only a whole-of-society approach can prevent the factions responsible for the January 6 attack from organizing online to cause future havoc offline.
