They would have been directed to behave this way by their leader, Newton.

"Guys what we are trying to achieve here is going to get Insurance companies do something that they never have done, and do not do for anyone else in the community. Having injuries that could have been caused by our work, but haven't surfaced for years later, is not something anyone in the world is covered for. It is not the NRL we are fighting for this, it is Insurance Companies and lawyers"
