I learned about two actually in my Govt class and my Hist 120 class just a year or so ago. Brown v. The Board of Education and Plessy v. Ferguson. Off the top of my head, since in an interview I wouldn't be able to jump on the 'net.

I think that Plessy v. Ferguson was the "seperate but equal" for education of blacks and whites was okay while Brown v. The Board of Education overturned that decision and said "no, it's not". *crosses fingers*

Would I have known more than Roe v. Wade before these recent classes? No.
