Milk became more interested in political and civic matters when he was faced with civic problems and policies he disliked. One day in 1973, a state bureaucrat entered Milk's shop Castro Camera and informed him that he owed $100 as a deposit against state sales tax. Milk was incredulous and traded shouts with the man about the rights of business owners; after he complained for weeks at state offices, the deposit was reduced to $30. Milk fumed about government priorities when a teacher came into his store to borrow a projector because the equipment in the schools did not function. Friends also remember around the same time having to restrain him from kicking the television while Attorney General John N. Mitchell gave consistent "I don't recall" replies during the Watergate hearings. Milk decided that the time had come to run for city supervisor. He said later, "I finally reached the point where I knew I had to become involved or shut up".
