USA...All shot up....

What is with the American kids shooting up their teachers and friends at their schools/universities? This is clearly becoming a trend.
The lastest....a 14 yr old boy who seems to have been suspended, arrived back with 2 hand guns and started shooting at people at his school. 5 injured [at the moment] and counting...
Why do these kids turn to violence? Is this now the new way of becoming a celebrity [even if you end up dying]...? How desperate does this kid have to be? What a sad society we live in....

It may be time to ban guns? Huh?!
