The real issue, already touched on, is the admin is not in charge.
Recall several years ago when many Hispanics walked off the job and ditched school on May 1 and called it, “Day without Immigrants”.
Ever since they have felt more empowered to promote their cause. Every Cinco de Mayo there is always some kind of problem like this in schools with a large hispanic population. And most don’t make the news.
High School and Middle School administrators know this and the smart ones will tactfully keep the juveniles from getting out of control without a strong arm approach.
From now on this school will have a problem every May 5 from this poor management.
