In the classic film noir Double Indemnity Fred MacMurray and his girl friend, Barbara Stanwyck, conspire to kill her husband for his life insurance by making it appear that he jumped off the rear car of a train.
Edward G. Robinson, playing a savvy insurance claims veteran, is suspicious.
I've got ten volumes on suicide alone. Suicide by race, by color, by occupation, by sex, by seasons of the year, by time of day. Suicide, how committed: by poisons, subdivided by types of poison, such as corrosive, irritant, systemic, gaseous, narcotic, alkaloid, protein, and so forth. Suicide by leaps, subdivided by leaps from high places, under wheels of trains, under wheels of trucks, under the feet of horses, from steamboats. But . . . of all the cases on record there's not one single case of suicide by leap from the rear end of a moving train.
Police department shave the same kind of data for homicides by race, occupation, gender, etc.
In light of the tragic events the other day at Ft. Hood, the cops better add another category: homicide by political correctness.
