MILWAUKEE (WTAQ) - The UW-Madison police chief says school shootings almost never happen without the shooter telegraphing intentions ahead of time.
Susan Riseling made the observation Tuesday during a panel discussion at the national attorneys general conference in Milwaukee. This week's summit is focusing on child safety.
Riseling said she has studied school shootings -- and inevitably, the attackers plan and prepare their assaults. She says it's the best time for authorities to intervene if they can.
It happened in Green Bay a few years ago, when a student told a teacher about two classmates working on a shooting massacre.
Colorado officials say they've been working on an advance warning system which encourages kids to speak up when they hear something. That state's attorney general, Cynthia Coffman, said her program involves anonymous tips.
She says the program has helped officials prevent 28 planned school shooting incidents over the past nine years.
