I now live very happily in Australia. It's not perfect by any means (nanny state comes to mind), but I feel safer here. More importantly, my wife feels safer.
The issue was never one of safety, the odds were never high that you would be on the receiving end of one of these SWAT attacks. The issue is the rights of citizens and their protection from unwarranted searches and unreasonable uses of force.
Australia has it's own issues on that front, look up Labor's recent proposal of data retention for electronic records or the infamous great firewall of Australia.
And as far as government's with regulatory zeal go, you've hit the motherload.
It's a lovely country (I've spent the last three years in Sydney and really and truly loved it) but don't kid yourself about the level of government intrusion in every. last. bloody. thing. It's maddening.
The safety issue is not about the government but the level of violence in general society, schools, etc. IMHO, Australia as a whole is a safer place to live than the US right now. You don't hear about people shooting up schools, etc in Australia because it doesn't happen. It feels to me that the rate of this type of incident in the US is increasing.
As I said, Australia isn't perfect by far. But at least the government isn't ignoring its core, founding principles like the US government has been doing the last couple decades.
I did mention nanny state in my original comment. To each their own. :)
