FILE – This Oct. 10, 2012 file photo shows Madonna performing on the “MDNA” tour at Staples Center in Los Angeles. Some Colorado fans are upset after music superstar Madonna used guns during a performance. Madonna started her show Thursday, Oct. 18, at the Pepsi Center in Denver with a gun scene, which she has used in previous performances. TV station KUSA received several calls Friday from concert-goers saying they were offended she used guns and violence as part of her show in light of recent events in the state that included a mass shooting at a theater during a Batman movie on July 20 that left 12 people dead.
