“Crimes conceived in hell don’t have angels as witnesses”

“Crimes conceived in hell don’t have angels as witnesses” is a saying often used in criminal law. To prosecute criminals, district attorneys often have to use witnesses who are “less than angels” to testify against them.
 
“The government cannot produce angels as witnesses to agreements made with Mr. Chagra in hell” was said by an assistant U.S. attorney in 1979. “For a plot hatched in hell, don’t expect to have angels as witnesses” was said by the assistant district attorney at the trial of John DeLorean in 1984. “When you go to prosecute the devil in hell, you wouldn’t call angels as witnesses” was cited in 1989. “Crimes conceived in hell don’t have angels as their witnesses”—the now familiar form of the saying—was cited in print in 1993.
