Possibly staging for incoming Antifa/BLM riots when people are not inaugurated or arrested?

No idea, but based on all credible data available to citizens, the mobilization doesn't make sense based on narrative being pushed.

I may be wrong or it has changed, but I thought Biden announced his inauguration was going to digital. Why would we be clearing any buildings around the National Mall with Line of Sight that may be used as a snipers perch?

I guess we all shall expect the worst, Biden Innagurrated, but hope for the Best, the assault on America stopped cold.
