Are there qualifications to be a Justice? Do you have to be a lawyer or attend law school to be a Supreme Court Justice?

The Constitution does not specify qualifications for Justices such as age, education, profession, or native-born citizenship. A Justice does not have to be a lawyer or a law school graduate, but all Justices have been trained in the law.

I kinda wish Sonic Youth would update lyrics for Youth Against Fascism. They can keep the verse about Clarence Thomas, though.

Black robe and swill
I (still) believe Anita Hill
Judge will rot in hell
