CWBCHICAGO was founded in 2013 by five residents of Wigleyville and Boystown who had been discouraged with inaccurate information that was provided during meetings of the local community policing (CAPS). Our coverage area has since been expanded to cover Lincoln Park, River North, De Loop, Uptown and other North Side areas.
