I lived in a town in my high school days that had a full fledged race riot over the shooting of a black teen who had broke into business . I have experienced what a riot does to a community. Peaceful protests are one thing , riots are another.
A riot is an undeclared war on a community, firing warning shots at the enemy probably isn't a good idea when fighting a war.
Take care, and if a riot breaks out in your community let me know how those warning shots work out for you.
