It's sad that this sort of thing has to happen but it's nothing new. Back when I was in high school '67-'70 at Ramona High in Southern Ca. shootings & stabbings happened every week either on campus or in the catwalks going to & from school. We were constantly having race riots, white's vs. black's, black's vs. hispanic's, hispanic' s vs. white's. And this was supposed to be the era of the love child.
I believe ever since those times people have lost all respect of others as well as themselves. that also accounts for parental guidence as they were a product of those times. It's time to be able to punish children without the fear of being sued or jailed for justifiable punishment.
