The photojournalist Eric Durchschmied was caught in Russia "back in the day" with a young female in his room. No hidden cameras, the door was flung open at the right "moment" and somebody took a flash photograph of him and a young lady who picked him up in the department store.
If they were hoping to blackmail him, they were disappointed, he just looked at them, smiled and asked if he could have a copy for his wife's solicitor, as he was getting divorced. They never contacted him again.
