No copyright is claimed in this video and to the extent that material may appear to be infringed, I assert that such alleged infringement is permissible under fair use principles in U.S. copyright laws.

Copyright Disclaimer Under Section 107 of the Copyright Act 1976, allowance is made for "fair use" for purposes such as criticism, comment, news reporting, teaching, scholarship, and research. Fair use is a use permitted by copyright statute that might otherwise be infringing. Non-profit, educational or personal use tips the balance in favor of fair use.
