Clad in bright-red mesh basketball shorts and a red shirt, 39-year-old Mark Felix wasn’t exactly inconspicuous when he approached four young women at different times in Boston’s busy Downtown Crossing on the sunny afternoon of July 10, 2008. He supposedly wanted directions to the Back Bay neighborhood. When he had his target cornered, he exposed his erect penis that was sticking out of the top of his shorts. Later that afternoon, members of the Boston Police bicycle squad arrested him in the same area. In his 2009 trial for four counts of open and gross lewdness, Felix chose to represent himself.
