A documentary by Libertarian radio talk show host Larry Elder entitled Michael & Me countering the gun control views of famous documentarian Michael Moore. Michael Moore of course has made such documentaries such as Roger & Me, Bowling for Columbine, Fahrenheit 9/11, and Sicko. This video will run about an hour and 30 minutes so if this interests you give yourself some time to enjoy.
