School Shooting in California

There was another school shooting today. AOL News has live coverage from a California station, but it doesn't exactly have the information straight right now because it's all by word of mouth at the moment. It is confirmed there are two people shot, and they are in critical and serious condition.

They are not exactly sure why there was a shooting, or if it was an accident. Still, if it was an accident, the student should not have had a gun on them. How would he even get ahold of a gun at that age? I am very much against violence, and it sickens me to find out about another shooting.
