Throngs listening to the leader at a rally, performing gymnastics for him and party officials (a Communist specialty), or lining the streets to cheer his motorcade - these are all "good crowds." In authoritarian states and declining democracies, good crowds exist in relation to dangerous ones, like the hordes of foreigners reportedly breaching U.S. borders, or protesters said to be committing violent acts. Democratic erosion and the criminalization of dissent go hand in hand. ]
