“For when tyranny is rampant” and not “For them tyranny is rampant”; apologies for the typo. Correction has been duly made:
“There is danger in civil disobedience only because it is still only a partially tried remedy and has always to be tried in an atmosphere surcharged with violence. For when tyranny is rampant much rage is generated among victims. It remains latent because of their weakness and bursts in all its fury on the slightest pretext.”
