One of the best known instances of Comstock’s decoy system for securing arrests was that of William Sanger. As described by Mr. Sanger in a written statement prepared for his trial and which the judge allowed him to present only in part, the circumstances were these. On December 18, 1914, a man had come to his studio, saying that his name was Heller, that he was a dealer in rubber goods and sundries, that he had read Mrs. Sanger’s booklets “What Every Girl Should Know” and “What Every Mother Should Know,” that he had enjoyed reading them and was in sympathy with her work. He then asked for a copy of the pamphlet on family limitation. Mr. Sanger said he had none. The man insisted, asked if Mr. Sanger could not find one around somewhere for him, as he wanted to reprint it in several languages for distribution among the poor people he worked with and with whom he did business. Mr. Sanger took the trouble to hunt about among his wife’s belongings and found a single copy of the booklet, which he gave to the man. A month later Anthony Comstock appeared and arrested him for having given contraceptive information contrary to the New York law. The man who came to him as Heller, was in reality Comstock’s spy. His real name is Bamberger and he is still in the employ of the Society for the Suppression of Vice. Mr. Sanger stated that Comstock on the day of his arrest had offered to get him a suspended sentence if he would plead guilty. Mr. Sanger declined and he was sentenced to thirty days in the workhouse, which sentence he served. This leads logically to the next consideration, namely, the place which Comstock gave in his own mind, and thus in the laws he framed, to contraceptive knowledge. And again let him first speak for himself. In a letter which he wrote on April 28, 1915, to Mrs. Clara Gruening Stillman, Secretary of the National Birth Control League (the first national birth control organization in this country) he said: “A letter dated April 23, 1915, purporting to have been sent out by you as Secretary of the Birth Control League, has been referred to this office. In this letter you say, ‘The law, both State and Federal at present makes it a crime even for physicians to give information as to methods, no matter how essential such knowledge may be to the physical and economic well-being of those concerned.’ There is not a word of truth in this statement, and you cannot find a single case, since the enactment of these laws, to justify such a statement on the part of your League.” Further on in the same letter he says: “I challenge your League to produce a single case where any reputable physician has been interfered with or disturbed in the legitimate practice of medicine. Do not make the mistake, however, of classifying the quack, and the advertiser of articles for abortion and to prevent conception, with reputable physicians.
