A few days earlier, just six months before Russia hosts the 2014 Winter Games, Mr. Putin signed a law allowing police officers to arrest tourists and foreign nationals they suspect of being homosexual, lesbian or “pro-gay” and detain them for up to 14 days. Contrary to what the International Olympic Committee says, the law could mean that any Olympic athlete, trainer, reporter, family member or fan who is gay — or suspected of being gay, or just accused of being gay — can go to jail.

Earlier in June, Mr. Putin signed yet another antigay bill, classifying “homosexual propaganda” as pornography. The law is broad and vague, so that any teacher who tells students that homosexuality is not evil, any parents who tell their child that homosexuality is normal, or anyone who makes pro-gay statements deemed accessible to someone underage is now subject to arrest and fines. Even a judge, lawyer or lawmaker cannot publicly argue for tolerance without the threat of punishment.
