I'm a US/AU dual citizen and I've visited America quite often over the last few years, and it feels like we hear about the shootings only very slightly less in Australia than in the US. Here they're still front page news, and my co-workers are all talking about them.
Had some friends from San Diego and Houston over in the last few weeks and the commented on how safe Sydney feels, even in the grimy parts. They said that they had a need for situational awareness at all times in the US, but here it feels like it wasn't so necessary. At this point I'm certainly not looking at America as the safe haven of liberal democracy or freedom. I feel freer walking around the streets near public housing here than I do in the financial district in SF. But I guess in America you get to own guns with a high clip capacity, bump stocks, and get to post white nationalist manifestos on message boards? Cool.
