Stewie,
In the liner notes to his "Thumb Thump" CD Joel Mabus writes about St. Louis, "It was there that Duncan (a black man) shot Brady (a currupt white cop) and a riot erupted." He places it "a few years" before 1899. I have not run across any real corroboration on that story. I'll try to follow the link you provided...thanks!
On a different topic...the electric car. It is interesting, many of the versions have Brady driving an electric car (or lectric car)but somehow Harvey Reid has him in a Caddilac car. I believe electric cars were not uncommon from about 1915 to abour 1925. The good thing was they were not hard to start as most of the internal combustion cars of the time...you just turned it on and went. I understand they were popular with Doctors. Bad thing was short range and short battery life resulting in high operating cost. Maybe only Doctors (and crooked cops) could afford them.
