These were absolutely randomized. Under my command, we have drug and alcohol buses. These are very large buses that we put on freeways and put everyone through the bus. The whole freeway will be blocked and we'll filter people through. This is for general deterrence and a good result for that activity is one in 44. My highway patrols are single-officer patrol vehicles. If they detect people driving erratically, their strike rate is as low as one in three. When you combine it, that's how we come up with one in 11 for the 100,000. We practise general deterrence on our drug and alcohol buses, but when our highway patrol detects people driving erratically, one out of three come up positive in tests.
