A man in an Adam West-worthy Batman suit scales a balcony at Buckingham Palace. According to this Los Angeles Times report, as reprinted on the registrationless Arizona Republic site:
He unfurled a banner that said, "Super Dads of Fathers 4 Justice Fighting for Your Right to See Your Kids," and remained there for about five hours. A partner, dressed as Robin, was stopped by guards before he could reach the ledge. Both men were later arrested.
The stunt was meant to demonstrate, the men said, that every man is a superhero to his children. Tell it to Dr. Wertham.
