Bob, I had one of those Beethoven sweatshirts. lol! As for your question, the simple answer is liberals. People who want to go along to get along. To give all the breaks and take the easy way. I just wonder if this was a board initiative or the administration and teachers.
I have a teacher in my neighborhood who said the high school hasn't really enforced the dress code in quite some time. She told me that when sent to the office very little happens to the offending student. Better to have no law than to have them and not enforce them.
