How can I tell how good my State's anti-bullying laws are?

The Bully Police assigns grades to States. Indiana gets a B+ for its anti-bullying laws a B+.

Does that mean bullying does not happen here? http://www.bullypolice.org/in_law.html. Of course not. Every day, children are bullied in Indiana schools. http://www.wishtv.com/Global/story.asp?s=6894166, http://www.wishtv.com/Global/story.asp?s=5318312
