Stephen Close was arrested, jailed and expelled from of the British army in 1983 for having sex with a fellow squad mate. Thirty years later, police in the English city of Manchester tracked him down and demanded that he give a sample of his DNA. Human rights campaigner Peter Tatchell says Mr. Close is one of three gay men convicted under Britain’s now-defunct indecency law who have been ordered to supply their genetic material to police.
