I have little sympathy for the USA and their gun culture. Sorry for the victims, but with their lax gun laws America must expect that the nutters will always be a problem. Although every country will have a nutter go mad now and again (as we have seen here) at least other countries try to keep some control and have some sort of regulation. I think NZ is lax but of course the US is worse. It seems that the killer only needed to produce a Drivers Licence and his cheque book and he was away with his Glock pistol.
Is this what the Founding Fathers wanted - I don't believe so. Of course the US is working under a document with few changes originating from the 18th century. And 2007 is a radically different place.
Then it could be said we in NZ are operating (for some) under a document from 1840 - and 2007 is a radically different place!
No matter what they say nothing will change in the US and it will happen again.
