I can tell you this having seen school violence (far worse than what these kids were planning) first hand and loosing friends to it. I can tell you that the impact of even a threat like this effects every one in the school. These kids need help and they need intervention now. For a group for third grades to plot and try to carry out an attack is a huge thing. who is to blame?? The list is to long and I wont go into it. But I can tell you these kids need help fast.
