UNDER the heading “The Mob Spirit Growing,” the Chicago Tribune of July 7 says:— The old and respectable city of Evansville, Ind., had a taste of mob rule last Sunday. A policeman was shot and killed, and, as the murderer was a negro, evil disposed individuals set out to lynch him. Not being able to get the murderer, the mob began attacking all the negroes it came across. Some of the black men tried to defend themselves. That infuriated the rioters, who do not concede to the negro the right of self-defense. Probably if an Evansville policeman had been killed by a negro two years ago, or even one year ago, there would have been no rioting, but to-day the mob spirit is rife in many Northern cities. Lawlessness in one community inflames the lawless element in another community, and it lays hold of the first opportunity to break the law. The lynchings at Belleville and Wilmington and attempted lynchings at other points were one great cause of the attempted lynching at Evansville. . . . In view of this prejudice, and of the growing inclination to resort to lynch law in Northern communities, it is the duty of peace officers, whether sheriffs or chiefs of police, to be more vigilant and efficient than they have been in many instances, and to deal with mobs in a decisive and ungentle manner. Otherwise the contagion will spread, and there will be riotous demonstrations in many communities now looked on as conservative and law abiding. The contagion of mob lawlessness is certainly spreading fast. The fact is visible to all, but its cause and meaning are clear only in the light of divine revelation.
