JFK is one person that Americans have never stopped mourning. and the Sixth Floor Museum in Dallas. on 411 Elm St. hosts a memorial for the last minutes of his life in the building from which Oswald fired those infamous shots into the nation's heart. The exhibits are exhaustive and display a city's apology for unconsciously being the scene of a tragedy of almost epic proportions. That day and beyond are reconstructed in the eleven sections: the Corner Window. the Crisis Hours. the Investigations. etc. The media reports of the period of time connected with the tragedy are included in the research wing.
