Jeez, just what exhibitors and studios don’t want or need after the Aurora tragedy. A 56-year-old man whom police say has a valid permit to carry a concealed weapon accidentally shot himself in the buttocks inside the Century 14 movie theaters in downtown Sparks on Tuesday night. No one else was hurt as about 30 people were watching The Bourne Legacy. Witnesses told police the man immediately got up, apologized to those around him, and left the theater before cops arrived. He later was found seeking medical treatment at a Reno hospital. Time for metal detectors?
