Whenever these things happen you have to remember this from Aleksandr Solzhenitsyn’s masterwork, “The Gulag Archipelago”:
Part I The Prison Industry, Ch. 1 “Arrest”
“What would things have been like if every Security operative, when he went out at night to make an arrest, had been uncertain whether he would return alive and had to say good-bye to his family? Or if, during periods of mass arrests, as for example in Leningrad, when they arrested a quarter of the entire city, people had not simply sat there in their lairs, paling with terror at every bang of the downstairs door and at every step on the staircase, but had understood they had nothing left to lose and had boldly set up in the downstairs hall an ambush of half a dozen people with axes, hammers, polkers, or whatever else was at hand?”
Those who fail to learn from history are doomed to repeat it.
