January 6 vs. September 18: How law enforcement hopes to prevent another riot

A new fence, an information-sharing alert and ramped-up airport security are just a few of the ways law enforcement is preparing to prevent another deadly insurrection ahead of Saturday's rally aimed at showing support for those arrested on January 6.

Criticism of the security failures around the US Capitol riot last winter has loomed large in the minds of federal officials and law enforcement partners ahead of Saturday's right-wing rally, resulting in a concerted effort to avoid the mistakes of eight months ago that left front-line officers unprepared for the violence that unfolded.

This time, officials are preparing for the worst and erring on the side of caution. Unlike on January 6, officers are well aware of the threats related to Saturday's event, which is expected to be a much smaller gathering with some spreading the false narrative that federal agencies will use the rally as an opportunity to arrest attendees.

The Department of Homeland Security issued a warning Thursday about the potential for violence from people involved in or opposed to the "Justice for J6" rally.
