As far as I am aware we had already changed the planned route to get to the ground and the police released this information before the day.Thanks for that. I hadn't seen that particular clip before and it serves to reinforce the poor policing of the incident. It seems to be on the corner by the Arkles and the turn is off the dual carriage way into the short stretch up to the ground which would make an ideal ambush position with everything being quite narrow and compressed. The police should have had a plan B with a diversion of some sort.
The whole thing does not reflect well on the fans or the police but more so on the media who did little to condemn the animals.
