That's the most famous (or infamous, take your pick) image from the prolonged white resistance to forced busing in Boston. The mostly Irish, blue-collar whites of South Boston fought long and hard against busing from September of '74 until just after the time of that photograph in '76. The system loves to use images like that to demoralize whites, ala black demonstrators getting hosed down and attacked by dogs in Birmingham and other Southern cities, and that one was shown to Bostonians over and over and over and over again.
The resistance by Boston whites to forced busing was the last large-scale white resistance in America. Some observers, myself included, believe the fight against the late '60s counterculture and its overthrow of traditional white values and ways of life was all but extinguished from whites by the mid-'70s. From then on, other than occasional incidents and flare-ups which continue to this day and still offer us at least some hope of eventual counter-revolution against this country's destroyers, whites capitulated to the counterculture, then disco and the general hedonism and gross materialism (and feminism and the pseudo-worship of minorities) that keeps white Americans in their place. <!-- Message ''"" -->
