This matter of lynching would be a terrible thing even if it stopped with the lynching of men guilty of the inhuman and hideous crime of rape; but, as a matter of fact, lawlessness of this type never does stop and never can stop in such fashion. Every violent man in the community is encouraged by every case of lynching, in which the lynchers go unpunished, to himself take the law into his own hands whenever it suits his own convenience. In the same way the use of torture by the mob in certain cases is sure to spread until it is applied more or less indiscriminately in other cases.
