i think there's two issues here:

1) girl being bullied
2) one helluva courageous kid

while i dont condone what the girl did, what drove her to this length to bring a gun to school? it would be interesting to know what the girl was going through.

it seems to me that bullying is worse than it was in the past. this is just my opinion. but what makes it worse now too is that people that should have, but do have easier access to guns and are willing to get their revenge with them.
