Among those arrested Saturday was DeRay Mckesson, a prominent leader of the Black Lives Matter movement. Mckesson, who released Sunday, live-streamed his arrest on Periscope.

"Arrests were inevitable," Col. Michael Edmonson, supervisor of the Louisiana State Police, said in a statement Sunday. "Our troopers maintained their poise and demeanor and focused on the job at hand, all the while enduring angry epithets and an occasional water bottle hurled from inside the crowd."

Edmonson told the Times-Picayune newspaper of New Orleans that some officers were struck in their heads by hurled as police chased a large crowd after a tense standoff.
