Plenty of clues in the pic. What is being protested? What unique name did these protesters give to their group?
Answer:This is a queer group protesting the shooting of the movie ‘Basic Instinct’, opposing the apparent portrayal of homosexuals in a negative light. The protest could stop neither shooting nor release of the movie. So they called themselves ‘Catherine did it!’, and took out posters and pamphlets in order to spoil the suspense of this murder mystery. Catherine Tramell (Sharon Stone) would be the murderer.
