We can't know how much of this is true or how much it contributed to the tragedy in Weston. What we do know is that nearly a third of America's school children say they've been the victims of bullying - or been bullies themselves - or both.
We know bullying can destroy a student's self-esteem and ability to learn. We know it can ruin students for the rest of their lives. It can ruin families and ruin schools.
We know it's a problem among girls and boys. We know it can be mental bullying as well as physical. We know it can border on torture for the young minds that are the victims of it.
It's a problem that affects us all. As such, it's a problem we must all help solve.
That's why we're partners with the Wisconsin Department of Public Instruction, which just launched its curriculum to help teachers cope with bullying in their classrooms, halls and playgrounds.
The DPI curriculum, called "Time to Act - Time to React," is a set of lesson plans to help teachers identify bullies and bullying and to teach their students how to deal with it.
The WEA Trust, a not-for-profit group health insurance company that insures many of Wisconsin's public school employees, paid for the printing of 1,200 sets of the curricula (one for grades 3-5, another for grades 6-8), and a free, interactive DVD available to teachers in any public grade school and public middle school.
This isn't a state mandate. It's not a requirement. It's a helping hand for teachers who feel they need the extra help to keep their students safe.
The problem is clear. So are the goals.
We, along with a large coalition of groups including those with a focus on schools, mental health, law enforcement and child advocacy, are supporting this effort to help keep our schools safe and healthy.
That's important for insurance companies that feel good mental health is important to a healthy body.
That's important for the wife of a murdered husband whose life was abruptly ended by a young boy out of control.
We're encouraging teachers to use the new curriculum. We're encouraging parents to be aware of what is happening with their children at school. This curriculum is a step in making teachers' and children's lives safer today and tomorrow.
