>>Everyone knows why -- NRA + gun manufactures + money + lobbyists + idiots + chickenshit congress members = no new gun laws.
NZ doesn't have a second amendment. Also worth noting that previously fairly strict license vetting was changed late last year by the same government that moved so quickly this time, which had allowed some licensing to be undertaken online rather than via local police. Scuttlebutt is that the Australian terrorist got his license at about that time. He also broke the law, modifying weapons to make them "E" category weapons that aren't allowed to standard license holders. In any case, pride cometh before a fall, and a big thanks to the Australian who brought all this nasty stuff to somewhere that didn't want any of it.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
