Where does it classify Whitman as a "sniper"? Oswald was not a "sniper". He was designated a "marksman" in the military, which is neither the same accuracy as a sniper, nor functions as a sniper. The man who shot Kyle, Eddie Ray Routh, wasn't a sniper at all, just simply an ex marine suffering from PTSD
You throw accusations every which way, without 1 neuron of thought behind them, outside of some preconceived mindset of what must have been the case. There are thousands upon thousands of snipers, in U.S., history and the best you can do to support the accusation that a "high percentage" return as murderous loons, are 3 examples that doesn't include even 1 designated sniper?? I think the "sick puppy" is the one making up all this crap
