Lippman and the Lieutenant - The Rap Sheet

I watch that series in re-runs on TV.
Panzer found a fun quiz game at The Rap Sheet site.
If you're a fan of the Columbo TV series, J. Kingston Pierce has put together a twenty-one question quiz for you. There's a link to the answers included in the post.
  Panzer says, "Nobody would look at the answers before the quiz, right?"
 Note: This is a short medium length post. Bring a cup of tea to drink while you answer the questions.
