Well of course results vary from paper to paper. I'm sure we all know that science progresses as general consensus. It's important to follow larger trends, not the day to day experiments.
I just don't know if this data is accurate. The people around me all make around 150-200k, but this graphic makes that out to be exceedingly rare. Yet I know I could do a quick search and find plenty of opportunities in that range.
Please don't make that argument about gun-free zones. In what world can we expect a person bent on mass homicide to respect municipal ordinance? Shooter: "Oh this sign says no guns? Darn, guess I'll abandon my murder spree then."
