DENVER (AP) - Some Colorado fans are upset after music superstar Madonna used guns during a performance.

Madonna started her show Thursday night at the Pepsi Center in Denver with a gun scene, which she has used in previous performances.

According to KUSA-TV (http://tinyurl.com/8kr7gdq ), the station 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.

Madonna and her agent could not be reached for comment.
