The Smithsonian Channel debuts a new documentary tonight on the assassination of Dr. Martin Luther King, Jr. that includes rare footage of the days leading up to the iconic Civil Rights leader's murder in Memphis in April 1968.
"MLK: The Assassination Tapes" relies solely on archival films, photographs and recordings from television and radio news coverage, as well as audio recordings of local police scrambling to secure the Lorraine Hotel minutes after King's shooting was reported.
