I have posted a couple of times before about taking two trips to Mississippi in 1964, for civil rights rights marches and such....but the 'moment' that prepared me for that was several years earlier, during the Little Rock school crisis....I was watching TV when they showed film of an elderly black man being harassed..(pushing, kicking...etc.) His 'offense' was walking too close to the school and getting noticed by a group of white students!

That image is still with me..
