In solidarity with SOPA and PIPA protesters today, I thought I'd round up some classic images of protest. These black and white photographs couldn't have much better composition if they had been planned. As it was, they weren't. That spontaneity adds to their story. (All prints are available in a variety of sizes and prices, as well as on stretched canvas, at All Posters.)
The image pictured above of a man being arrested is from the LIFE archives. It was captured at the 1968 Democratic National Convention.
Here, ministers and other ride a bus to protest against segregated transportation:
These two police officers look on during a hospital strikers' protest march.
This excellent shot was taken during a rail strike.
Not exactly sure what's going on here, but it certainly has an interesting narrative.
