The knock and announce requirement is not specifically in the Fourth Amendment because it predates that amendment by decades--it was a common law right long before the Constitution was written. I would, however, refer you to the Ninth Amendment.
Can't help but notice that many of the "Does it really matter? It only affects criminals" arguments here echo those of gun-grabbers with regard to the Second Amendment. The Bill of Rights is not a menu at a Chinese restaurant--if we do not have all of its protections, then we have none.
Were warrants also common law?

Guilty until proven innocent. So many people on this thread champion it and don't know that they've been manipulated into that position/stand. I want to hear them say they weren't manipulated into taking the "does it realy matter?"/guilty until proven innocent stand but that they came to the decision on their own. Lack of critical thinking in favor of letting their emotions guide them.
I guess people haven't noticed that we're busy criminalizing everything.
I predict that within two years, we'll see warrants issued against parents for allowing their kid to take a Twinkie to school.
