Valley movie theaters increase security following Colorado shooting

Movie theaters in the Rio Grande Valley are increasing security following a deadly shooting at the premier of the new Batman movie in Colorado.

Some 12 people are dead following an early Friday morning attack by a lone gunman in Aurora, Colorado.

Movie theater chains across the United States are reviewing security policies.

Attendance for "The Dark Knight Rises" remains steady at Valley movie theaters.

Theaters are requesting increased security and police presence for the screenings.

It's not clear what permanent security changes local movie theaters will make.
