And all this time I thought you were in WA (Western Australia).
Very sad news. We do get a few shootings over here but mostly bikers and organised crime. It's very rare for a domestic shooting and there are almost no accidental shootings.
I am a gun owner and have to comply with some very strict rules. A firearms safety course first and safe storage and transportation rules. There is a zero tolerance policy with even a minor breach facing a gaol (jail) sentence. It takes away spur of the moment decisions. I can't remember the last shooting that involved a licenced gun owner.
I was initially against our laws but now they have been in force for 20- odd years I am all for them. There are some silly parts to the laws but on the whole they work well.
