TUCSON, AZ - MAY 29:  Tucson Police Officer Angel Ramirez arrests a man for trespassing May 29, 2010 in Tucson, Arizona. Ramirez works in the city's predominately Hispanic south side. The Tucson Police Department is currently gearing up to begin training its officers on the implementation of the controversial new immigration law SB 1070. Although a Tucson police officer was one of the first to file suit in federal court challenging the new law, most rank and file officers tend to support the legislation while the Arizona Chiefs of Police have criticized it.
