The new head of Victoria Police’s Professional Standards Command is very cross indeed. I can understand his frustration but can't quite agree.

The suggestion is that, perhaps to fill quotas for random breath tests, the cops were sometimes just blowing into the breathalysers themselves. Over 5½ years, about 1.5% of tests might be ********.
Now as a personal rule of thumb, I expect the results of letting human beings collect data to be easily 5% garbage. So with a mere 1.5% of junk data, I'd like to congratulate the Victoria police as they're clearly exemplars of scrupulous dedication.
