                    Portland police official Earl Biggs publishes his book Sex, Science and Sin: A Study of Normal and                     Abnormal Sex Activity of Our Time in Relation to Science, The Law, and Religion, in which he argues                     for the decriminalization of consensual homosexual behavior. After 20 years on the police force                     investigating sex crimes, Biggs comes to the conclusion that society is unjust in bringing the criminal                     law to bear on consensual behavior. As a result of the publication, Biggs is contacted by Dr. Alfred                     Kinsey. The two develop a warm friendship. Biggs visits the Kinsey Institute the following year, and                     Kinsey comes to Portland a few months after that.

                    A Senate report titled "Employment of Homosexuals and Other Sex Perverts in Government" is                     distributed to members of Congress after the federal government had covertly investigated                     employees' sexual orientation at the beginning of the Cold War. The report states since                                         homosexuality is a mental illness, homosexuals "constitute security risks" to the nation because                     "those who engage in overt acts of perversion lack the emotional stability of normal persons."

                    Over the previous few years, more than 4,380 gay men and women had been discharged from the                     military and around 500 fired from their jobs with the government. The purging will become known as                     the "lavender scare."

                    Army Regulation 600-443 is published, identifying three categories of homosexuals. Those deemed                     to be aggressive are placed in Class I and are subjected to general court-martial. Homosexuals                     considered active but non-aggressive are placed in Class II and can avoid a court-martial by                     accepting a dishonorable discharge or resigning if they are officers. Personnel professing or                     exhibiting homosexual tendencies without committing a violation of the sodomy statute are                     designated “Class III,” and can be removed from service under general or honorable discharge.
