Bullying has been around forever- it's just that it's gaining more attention due to the media- I couldn't say if there is an actual increase- not without some sort of hard evidence or numbers.
Laws aren't gonna help, stronger or not. Kids are going to bully whether or not there are laws (I'd have to read up on these laws to see what they say- am curious).
Education, counseling and action IN the school starting at an early will help but I doubt it will eradicate it completely as there are many reasons why bullying happens.
I'd be curious to see how this turns out. I was bullied that young but I don't think it was serious enough to warrant a lawsuit.
