Victoria Police Commander Leigh Gassner denied that police had overreacted, saying it did not take much for an innocent act to spill over. "Even the ... Mexican Wave is pretty harmless but to put it into context, when you start throwing things then you can't take it lightly," he told reporters. "There's a cultural issue about where this is occurring and I think we have to say that that culture is no longer tolerated at the MCG anywhere * Anyone detected throwing items or starting the Mexican Wave throughout the ground will be automatically evicted; * On-the-spot fines, harsher penalties for invading the playing area and intensified bag searches will also be introduced, with details yet to be worked out. The tough stand follows a weekend of hooliganism during two matches at the MCG which resulted in 36 arrests and nearly 500 expulsions. Members of the ACB, the Melbourne Cricket Club (MCC), Victoria Police and the state government met today to consider how to address crowd misbehaviour. MCC secretary Stephen Gough told reporters the agreement on the measures was unanimous. "The idea is that we don't want to see cricket interrupted at the MCG and we don't want to see the future of cricket at the MCG under any threat," he said.
