I recall a photograph, taken in the late 1960s or early ’70s, during some sort of protest (it could have been anywhere, about pretty much anything, given the high level of unrest). A rank of soldiers stood in full combat gear, rifle barrels pointed straight up in front of their faces. They were at attention, with firm expressions, eyes forward. A slim, beautiful hippie chick faced one of the soldiers and was sliding the stem of a daisy down the barrel of his gun. She had been working her way down the rank, performing the same gesture with each soldier’s rifle, as they stood fast without reaction.
