Hmmm...this would of course, given the current price of Es, mean that the children 'accidentally' stumbled upon somewhere between six to seven and a half thousand pills...
The cops seem to always inflate the value of drugs that they seize (or have handed over to them, in this case). It makes it seem more impressive. Australia's largest ever ecstasy bust happened a few weeks ago, and the total "street value" of the pills being given by the cops would have meant that each tablet would sell for about AU$75, each, which seems to be a rather inflated figure. Or maybe the cops are just used to getting really bad deals.
As of 15:30 GMT today, the global exchange rate for AUD to GBP was 1 GBP = 2.78627 AUD. That means the Aussie police were valuing each tablet at roughly £26. Yes. I'd say that was an inflated price.
