When I read this I was waiting for some "statistically challenged" and/or "root cause analysis challenged" person to post this. Glad I wasn't disappointed but then it was fairly predictable.
For the "statistically challenged": One example like this does not make up for all the incidences that the media doesn't report. Case in point:
Family violence rates soaring in Hamilton. Now isn't it strange that an area like Hamilton which has been a dairy boom town should be have this happening?
For the ""root cause analysis challenged": The article simply states the outcome. But why did the woman feel the need to throw the knife? Was she being assaulted? Was it self defence? What's the background of this? Has the violence been going on for ages? Was she protecting the children? Hopfully the facts will come out but they're likely to be so familiar that the it'll go unreported except as part of a large number in family violence statistics.
Sorry Cuz, if all National supporters are like you we really should be focusing on what our education system turns out because it seems to be failing.
