That is correct. The lesson plan for that has been developed in conjunction with medical practitioners to ensure that the things we're looking for are well within the capabilities of the police officer. That is to say, for pupil size, we use a card called a pupillometer. It has dots on it in half-millimetre increments. You simply put the card beside the person's eye until you line up the pupil size to match the dot on the card. That gives you the size of the pupil.
