What are law enforcement officials expecting?

Law enforcement officials are bracing for potential clashes and unrest during the rally, according to an internal Capitol Police memo reviewed by CNN.

The latest intelligence report on the event notes that online chatter in support of the rally started increasing after the officer who fatally shot rioter Ashli Babbitt went public with his identity in a recent interview with NBC's Lester Holt.

There's been a noticeable uptick in violent rhetoric around the event and heated discussions centered on Babbitt's shooting on social media and discussion boards, according to the memo.

The document warns that many individuals may also see September 18 as a "Justice for Ashli Babbitt" rally, which could be cause for concern, and it's not unreasonable to plan for violent altercations.

There have been additional discussions of violence associated with the event, with one online chat suggesting violence against Jewish centers and liberal churches while law enforcement is distracted that day.

Around 500 people have indicated they plan to attend, though the memo notes that past recent events organized by Look Ahead America had significantly lower attendance than expected and were peaceful.
