The main concern raised within the criminal justice section involving the instruments or the machines was focused on what's happening at the time an accused person is being tested on the machine. This takes on a much greater importance when that person is later restricted from being able to testify about how much they had to drink and to have evidence to the contrary considered by a court in the normal context.
I cannot say that we discussed in any depth the general maintenance of the machinery or the accuracy of the instrument in terms of its ongoing maintenance, whether it be monthly or yearly, or those types of things. It was more in relation to having a videotaped record of how the instrument was being operated at the time, because if the onus is on the accused to produce evidence that the machine is not working properly, or the operator is not operating it properly, what ability are they going to have to do that unless, after the fact, they can show somebody who does know about those things an independent record of what happened?
