I was a senior in HS during Columbine. They outright banned them for the rest of the year. I was also Goth, so yeah, but couldn't really dress like one. Especially when wearing black button down shirts made you look like the Jesuits walking around the school.
And our dress code specified no unnatural dying of the hair.
We had a President, a Principals, a Dean of *DISCIPLINE*, who was also the basketball coach (our football team was meh).
