Start with the first two points above by watching the Mr. Ed video and reading this from motherjones.com: “Lautenberg’s [Denying Firearms and Explosives to Dangerous Terrorists Act” (S.34)] would give the Attorney General the authority to stop the sale of guns or bombs when a background check shows that the purchaser is a known or suspected terrorist, and the AG ‘reasonably believes’ that the person may use the weapon in connection with a plot against Americans.” Parenthetically, “(One problem: many people on terror watch lists are not in fact terrorists.)” What could possibly go wrong? See: above.
