Some interesting videos to watch.

"Most of what you think you know about our Constitution (and government) is wrong."

Long time historian, author, trainer and public speaker, Michael Badnarik addresses the sheriffs in attendance Monday morning. He explains to the over one hundred sworn officers in the room how what they think they know about the Constitution and Bill of Rights may not be entirely accurate...Michael Badnarik: Rattling the Sheriffs' Cages About the Constitution

NOTE: "The post event feedback surveys clearly indicated that this kind of training on the Constitution was the number one component that sheriffs wanted more of. "

"On January 30-31, 2012 over 100 county sheriffs and peace officers, from over 30 states, united to uphold their oaths of office, protect citizen liberty, and stop state and federal tyranny. Inspired and led by the example of former Graham County Arizona Sheriff Richard Mack, the meeting, which was held in Las Vegas, was funded by the generous donations of thousands of Americans from all fifty states, as well as the support of freedom loving sponsors.  The agenda included training on the Bill of Rights, Interposition, Nullification and the importance of Property Rights versus Privileges.  Many sheriffs, a police chief and even a county commissioner shared their experiences, challenges and actions taken to uphold their oaths of office, directly with the sheriffs in attendance."

There are longer versions of these 1-43 videos which are all about 6-9 mins long so you can watch them as you can. At least if you are going to use the Constitution to defend yourself you should know what you're talking about or get a education on it specifically..

Michael Badnarik's Constitution Class 1 of 43

"In the early eighties Michael Badnarik started his career as a computer programmer at an Illinois nuclear power plant. For the past twenty years he has continued this professional course, but during this time he became interested and frustrated with politics. As a result, in 1983 Badnarik began studying the IRS and then the constitution.

He had since condensed his 18 years of research into a short eight hour course that he would teach in a lecture format. It included some of the fundamentals on our rights and the foundations of our republic. A video recording of one of the classes has been made and you can watch it here.."
