I think I said my piece about guns in society in a previous post a year or few ago. I sort of embarrassed myself. But guns are illegal here in Australia, unless you are member of a shooters club or a farmer. But regardless, this limits you to what guns you can register & own.
Of course this is not to say illegal guns do not get around because they do. But there's a nice little jail term for being caught with one. Minimum 2 years jail from memory.

I know I know, Charlton Heston demanded guns be allowed for every man woman & child in the USA for self protection. (was that due to his senility?) ... And how many school shootings have there been over past 10 years?

(Oh is that a burglar .. * BANG * *BANG* * BANG* .. yeah think we got him .. OMG ... oops it was our daughter sneaking in late ! )

You only need to look at the crime rates of countries that legalise guns & those that don't (including the accident examples like mine above of course which are often left out of *true* statistics.)
