Flip, here in NZ, I remember when everytime there was a murder it was splashed all over the front paper, reported at length on TV and the Radio - now, its just a tiny snippet on page 3 of The Herald.. And only violent crimes which involve old people or kidnapping (we dont have many of those) are featured on the front page. Oh, but if the All Blacks win during the time that someone else is stabbed to death on the street, than Duh - of course ABs get the front page.
Consequence of desentization: escalation of violent crime - and I totally reckon that crims will allovasudden become more creative and use the country as the setting for a Chainsaw Massacre/Saw sequel - tryna get that attention.
