Last Sunday night more than a thousand people came together at Denver's Tracks nightclub in a vigil for the victims of a mass shooting in Orlando, Florida. Among those holding candles and standing quietly near the back of the gathering were uniformed officers of the Aurora Police Department, reminding those present of the link between the Orlando shooting and the movie theater attack in their own city four years ago.
