If no dogs were used in this exercise then how could a dog handler be properly assessed? Does he run around, cocking his leg up and eating biscuits that the assessor should throw? As it stands, by not using dogs, it makes the exercise useless. Instead of one man with a pretend dog not inspecting the traps, the examiner is also culpable for not marking the handler as a 'failure'. It's all a farce and if it was us, the media would have a field day in slagging off a 'comedy club'.
But FWIW, maybe what happened was intended. Graham Souness seems suspicious about it, having being frisked on entry to the stadium for the first time, and with this in mind then maybe it was really an evacuation exercise to see how quickly 50k+ people could be evacuated from a stadium but it could only be agreed by using a real time match with no realistic issues to be solved. A dead rubber game like this would have been a perfect choice for such an exercise.
