 Late in the night on July 29th, during the height of the 2020 Uprising in Portland (OR), as protesters gathered outside the Hatfield Federal Courthouse to fight for racial justice, the Department of Homeland Security (DHS)'s Customs and Border Protection (CBP) used a thermal fogger to deploy unknown chemical agents on the crowd:

 Broadly speaking, a fog is a visible aerosol that hangs in the air near the ground, and while it occurs on its own accord, humans have devised a variety of methods to generate fog.
 And many, if not all, of those methods have been used to deploy chemical weapons on people.
