68 arrested as protesters march to Churchill Downs, Cardinal Stadium

I could teach a decent patrol officer how to process that scene over the phone or by posting instructions on this site better than it was handled.

There wasn't a single point of failure in that regard. Schroeder and Chavous were at the scene. PIU has no independence from the chief's office or from Schroeder at the time. They worked for him and continue to work for him.
