Bradley was an Audubon game warden killed by plume hunters in 1905 offshore from Flamingo, a tiny fishing village a century ago. The man who shot him surrendered and spent five months in jail at Key West before trial. He pleaded self-defense and was acquitted. The case sparked a wave of resentment of the trade that collected feathers for hat-makers' use. In response, several states adopted bird-protection laws.
