The rise and sway of the gangster as a menace to American social and economic security has led, of late, to the employment of unique means of combating lawlessness. Faced by a tremendous increase in the difficulties lying in the path of those seeking the conviction of professional criminals for major crimes, the police and prosecutors often turn towards a means of fighting crime originally devised to make life uncomfortable for petty off enders. The enforcement of the pistol laws and the vagrancy statutes against millionaire gangsters, and repeated arrests on suspicion, have been resorted to as a means of harassing the habitual criminal, where superior organization and intimidation make almost impossible the securing of convictions on serious charges.
