Most important constitutional rule? Equal protection clause

Let's talk about the most important part of the Constitution - the equal protection rule. In particular, we're going to discuss the "equal protection" clause and how it relates to our civil rights. So we've spent the last few episodes talking about civil liberties , or our protections from the government, but civil rights are different as they involve how some groups of citizens are able to treat other groups (usually minorities) under existing laws. We'll talk about the process the Supreme Court follows in equal protection cases, called strict scrutiny, and look at one landmark case, Brown v Board of Education, and explain its role in starting the Civil Rights Movement of the 1960s.
