Third degree

From Wikipedia, the free encyclopedia

Etymology

The third degree is a widely used colloqualism for an intensive, possibly brutal, interrogation. This usage is derived from the Freemasons, an extremely popular fraternal organization from the eighteenth through the early twentieth century. Masonic lodges have three degrees of membership; the first is called Entered Apprentice, the second Fellowcraft, and the third is Master Mason. thr granting of the Third Degree involves an extended interrrogation carried out as a scripted play in which the role of the inductee is physically challenging and, to an inductee with a lively imagination, possibly frightening, although no physical harm is inflicted. This interrogation was, by exaggeration, the source of the name of the police interrogation technique. That is referred to in an 1900 edition of Everybody's Magazine: "From time to time a prisoner... claims to have had the Third Degree administered to him."
