Middle School Kids Out Of Control!

I am royally pissed at the outrageous behavior and violence occurring at my children's middle school.  On Monday I walked in to help set up the spring Scholastic Book Fair to see a fight right in front of the Principal's office!  On Tuesday afternoon, I witnessed another fight in the same location right after school.  My daughter informed me that there was a fight earlier in the day at lunch.  And this is not an inner-city school!!!  This is Foothill Middle School in affluent Walnut Creek, California!!!!  What the hell is going on around here!!!!
