If you saw a man standing outside the grocery store swinging a baton and glowering at passers-by, would you go inside?
Perhaps, but more likely you would decide you didn’t need arugula that night after all. True, the baton wielder never actually said, “Buy arugula and get beat down,” but then he didn’t really have to, did he?
Similarly, a man standing in front of a voting precinct would send equally unmistakable and threatening signals. On Election Day 2008, two men were famously filmed — one brandishing a weapon — in front of a polling place in Philadelphia.
