"The individual in question, a cook out of work, whose chief reason for being at the Bastille was idle curiosity as to what was going on, esteems, that since such is the general opinion, the action is patriotic and even believes he deserves a medal for having destroyed a monster. With a sword that is lent him he strikes the bared neck, but the weapon being somewhat blunt and not cutting, he takes from his pocket a small black-handled knife and (in his capacity of cook he would be experienced in cutting up meat) successfully effects the operation." The working of the process indicated above is clearly seen in this example. We have obedience to a suggestion, which is all the stronger because of its collective origin, and the murderer's conviction that he has committed a very meritorious act, a conviction the more natural seeing that he enjoys the unanimous approval of his fellow-citizens. An act of this kind may be considered crime legally but not psychologically. The general characteristics of criminal crowds are precisely the same as those we have met with in all crowds: openness to suggestion, credulity, mobility, the exaggeration of the sentiments good or bad, the manifestation of certain forms of morality, &c. We shall find all these characteristics present in a crowd which has left behind it in French history the most sinister memories--the crowd which perpetrated the September massacres. In point of fact it offers much similarity with the crowd that committed the Saint Bartholomew massacres. I borrow the details from the narration of M. Taine, who took them from contemporary sources. It is not known exactly who gave the order or made the suggestion to empty the prisons by massacring the prisoners. Whether it was Danton, as is probable, or another does not matter; the one interesting fact for us is the powerful suggestion received by the crowd charged with the massacre. The crowd of murderers numbered some three hundred persons, and was a perfectly typical heterogeneous crowd. With the exception of a very small number of professional scoundrels, it was composed in the main of shopkeepers and artisans of every trade: bootmakers, locksmiths, hairdressers, masons, clerks, messengers, &c. Under the influence of the suggestion received they are perfectly convinced, as was the cook referred to above, that they are accomplishing a patriotic duty. They fill a double office, being at once judge and executioner, but they do not for a moment regard themselves as criminals.
