Wow, the natives are restless. "Had it coming"...really, taking someone's life because they are rude, really...if anyone really thinks that, please, get some professional help and by all means, stay away from guns until you can get it under control. There is NEVER an "okay" time to take a life except in war or to protect innocent life from grave harm and or death. Sure the "texter" may not have been "innocent", but he did not deserve death.

An armed society is a polite society only if people respect others. Rudeness is encouraged throughout the American culture, in fact brash in your face rudeness is no longer uncommon. We may be past that point in the USA where respect of our fellow man, much less his life, is still the common denominator.
