For what it's worth, if my wife calls 911 and tells them "Please send the police, I saw a prowler in my backyard", or "Please send the police, a kid on a dirt-bike just ran over my grandson in my driveway", I will be sure to have her also tell them "By the way, this in NO way grants the police permission to enter and search my house". Any effort to do so, without a warrant, is a violation of my rights.
PS, Rights not defended are rights soon lost.
