A large group of #BlackLivesMatter protesters, some tagging their tweets with #ReclaimMLK, shut down traffic in the Delmar Loop spanning University City and St. Louis, Mo., Saturday among a large police presence. The chaos was documented extensively in photos and Vine videos, showing just how short tempers have become. (As always, these Vines come with a language warning.)

Speaking of both police contempt and getting “so worked up” over an inanimate object like the American flag, enjoy this Vine video from a recent pro-police rally in Ferguson.
