Good for Australia and every other civilized society that is not awash in guns, not beholding to the NRA and truly cares about it's fellow citizens!
Unfortunately for the U.S. our president cannot pass a law until Congress acts first and we all know our pols in Congress want their jobs for life and would never cross the NRA...and the NRA knows it!
I notice Donald Trump spoke recently in Tenn and the topic of Oregon's mass shooting came up - on cue, he went directly to the 2nd Amendment, as if that has anything to do with this country being awash in guns, guns of all types! Say what you will about Trump, he does know his audience - he'd never get away with that crap in a more educated state that truly cares about it's fellow citizens!
Need further proof this nation is not as advanced as we think we are?...the probable 2016 Repub candidate for president had this reaction to Oregon's mass shooting, "Stuff Happens" and there was no outrage from Repub voters - NONE! Instead, we hear comments like Trump's (above) - Repub pols know what their supporters want to hear!
However, I will give the NRA this, they adopted FOX' business model and it works - make the American public afraid of their own shadow and they'll eat out of your hands.
