I've never heard of any incidents, where WWII vets were killed for a cause in DC. I am sure there were individual WWII vets killed in DC, just like anybody else might get killed.
Are you perhaps referring to the WW ONE bonus marchers, who came to Washington DC in 1932, broke and homeless from the Great Depression, trying to get the government to pay them a "bonus" from their WWI service early? The "bonus", a paid-up $500 life insurance policy, was not due until 1945. They built a "Hooverville" shanty town on the National Mall, and squatted in empty buildings. Many had their entire families with them. These were god-fearing, flag-flying patriotic American war veterans, who were broke and desperate. The Washington Police and the US Army (with MacArthur, Patton and Eisenhower on hand) finally burned their shacks and ran them out of town, with billy sticks and tear gas. Only a few, if any, of these vets were killed, but two of their children died from the tear gas.
