Just in case you hadn't heard already, students were sent home for wearing American flag t-shirts on Cinco de Mayo.

First, if the shirts are within dress code they should be allowed to wear them regardless of the day.
Second, when did a Mexican holiday (that most Mexican's in Mexico don't celibrate) become an AMERICAN HOLIDAY that dictated what clothes I can/can't wear?
Third, I bet if they were to ask all of the students, faculty, admin what the origination and reason behind this "holiday" is 99% of them would be wrong or have ZERO clue.

For the record, I would be the parent who was "detained" by campus police for yelling at the principle or staff member who told my son/daughter that they couldn't wear a t-shirt with the American flag on it because of a fake Mexican holiday in the United States.
