Marion Hammer, 79, head of the Unified Sportsmen of Florida, the state’s NRA affiliate, filed suit against four men in a Tallahassee federal court on Friday, seeking damages stemming from harassment and threats from the men received in the days following the tragic shooting that occurred at Marjory Stoneman Douglas High School. The 129-page lawsuit says that among the scores of profane remarks and graphic images Hammer has received over the past several months, urged by groups such as End the NRA, a few rose to the surface.
