These pictures were taken on Nicollet in front of Eat Street Dentists after the initial standoff between the first wave of protesters and federal agents. These pictures are not only for documentation but to familiarize other community on the types of weapons being used so they can gather more information on type and size (albeit no one should assume these are the only types of cannisters being used).
Taking a page from Hong Kong protesters, these look like they should fit underneath orange cones to direct the smoke and then use water to extinguish them.
