May 4, 1970

Federal troops, sons of WWII veterans, fired on unarmed college students, also children of WWII veterans, who were exercising their constitutional right to free speech. Forty years later, four families still grieve. And both sides are still sniping at each other.

Tin soldiers and Nixon coming,
We're finally on our own.
This summer I hear the drumming,
Four dead in Ohio.
(lyrics by Neil Young)
