It's always interesting to see how liberal propagandists try to spin every story. I guess the official line on this one is that the shooter was really only going to shoot that one person... Yeah, that's it; right. This argument can be made any time a killer is stopped.
It's very likely though that in at least some cases, if not many, a killer who is stopped would have gone on to kill again, and again, becoming a mass or serial killer, or a professional criminal who kills whenever it suits his purpose. Was this one of those cases? God only knows. But we can thank God, and the officer who stopped this criminal, that we didn't get a chance to find out.
