Hmmm...following around little kids...sounds like the Minutemen could make the case for them being child predators.
The problem better be taken care of legally by the authorities in short order or it's something that sounds like it could get out of hand in a hurry. You don't mess with someones kids.
The purpose of picketing the school is to identify the Minutemen kids for harassment and violence from a much larger number of hispanic kids which they will inflame with cries of 'racism' rather than 'illegal', knowing that school staff, most Black kids and a third of White kids will be on their side and the rest neutralized.
