The outrages of Ft. Hood and Orlando have become occasions once more for journalistic misuse of the language.
If you were shot but not killed, you were "wounded." The policewoman credited with stopping Ft. Hood's murderous Major is a "heroine."
Count, if you like, the number of times "injured" is referred to the many who were actually wounded, but don't bother to count the times the little lady shows up as a "hero."
