500

 500.

 That seems to be the problem.

Not increasing the existing group by 500 but recruiting and "training" 500. 

Policemen that is or nowdays I suppose, sworn police people.

Sworn at more likely.

Based on personal experience and observation 500 more bullies and liars who are a danger on the road and a joke off it.

Or maybe 500 more sheilas without a brain spread between the lot, far worse bullies than the fellows and grossly dishonest, every one of them.

500 bone-idle lazy dickheads who take the King's shilling, wear military-style uniforms (remind you of anyone?) and happily turn a blind eye when the wrong people are needing help.

Maybe I'm cynical (maybe?) but 500 won't do the trick.

Making the bastards now employed do their job, stand up to their vows and enforce the laws of New Zealand fairly and compassionably without fear or favour would be a far better way of spending tax-payer money.
