Door-to-door solicitation is a Constitutional right!
The Supreme Court ruled today that "The Constitution protects the right of missionaries, politicians and others to knock on doors without first getting permission from local authorities, the Supreme Court ruled today," says the Washington Post.

The case was "Watchtower Bible and Tract Society of New York Inc. v. Village of Stratton, Ohio, et al., 00-1737."

Coming soon: "Sensing v. Anybody Who Knocks on His Door," which will decide the Constitutionality of slamming the door rudely in anyone's face who pesters me with unwanted solicitations.
