7th Heaven - Season 10 Episode 12 Got MLK?

Racism comes to light at the high school when Alex, a new African-American student, wants to give a report on Dr. Martin Luther King, but his teacher argues that they have already covered that topic in class. When Martin inadvertently supports Alex's case, he falls victim to a hate crime. His car is defaced with racial slurs, and he refuses to wash it off until the culprit is caught. Meanwhile, for her own report, Ruthie attempts to recycle an essay that she wrote three years ago.
