Victoria Shadow Police Minister Brad Battin warns it should alarm every MP that riot police were needed to protect Pauline Hanson from violent protesters. “It’s disappointing to see on the streets that we see that level of protest outside of political events,” Mr Battin told News24 host Chris Kenny. “They think that if they become violent or threaten violence, they can get control. “It’s a concern for all members of parliament; this isn’t just one party; it should be a concern to every member of parliament.”
