According to the Sensible Sentencing Trust, our police are struggling to deal with a worsening "P epidemic".

That is scary and I fear it's true. Not so many years ago a violent crime was big news - these days it is almost a daily occurrence.
So why have we turned into a violent nation? What makes someone go from being a nice person to a nasty person? I can't believe all those criminals filling our jails were born bad.
In defending the claim that Kaitaia, a small town in the Far North, was the murder capital of the world, Mana Party leader Hone Harawira might just have the answer to those questions.
