Veteran land broker and appraiser Tom Bazan first got involved in the municipal arena when he launched a lead paint detection business and fought city contractors who were all too eager to ram through deals without completing proper inspections. From there he ventured onto Houston's transit battlefield -- first producing a Web site that urged the recall of city appointees to the Metro Transit Authority Board, and then e-mailing a sometimes daily antirail bulletin to a list of government officials (mostly Republicans) and media members. He was among the first to call attention to Metro's growing financial problems resulting from slumping sales tax receipts. While some folks have complained about receiving his unauthorized e-mails, Bazan claims innocence, noting that some of his willing recipients often forward the messages on to others. It just goes to show how one man's spam is another's exercise in free speech.
