I want to be crystal clear here... the Dayton police got violent first. As some protesters tried to outflank the line of bike cops, this officer, armed with a paintball gun, began firing on people.
The police then donned gas masks and began threatening to disperse the crowd violently. I saw water splashed from a water bottle above the frontline before the first wide spread use of pepper spray. The only injured cop I saw was suffering from the effects of their own spray.
