Movie Etiquette

Few crimes in this world should be punishable by death: Murder, Rape, Treason, Child Molestation, Talking on a cell phone during a movie. I do not understand it, why pay 10 bucks for a movie, and then talk on the cell phone during the film? Not to mention pissing off the entire crowd that happens to be in ear shot. The ushers should come up to the person on the cell, bust out the pistol, and deliver the cold lead of justice right then and there, no judge, no jury, no lawyers, no bs OJ “the glove don’t fit, you must acquit” crap.
