The Dal-Tex Building is most likely the sniper's perch from which Actual Assassin Of John F Kennedy fired the shot that killed the President during the John F Kennedy Assassination.
At the time of the assassination, the Dal-Tex Building was co-owned by a Jew, David Weisblat, a major financial backer of the ADL. Multiple floors in the Dal-Tex Building housed offices that used the telephone number of a Jewish attorney, garment manufacturer, and well-known figure in Jewish advocacy Morty Freedman.
At the time, One of the firms with offices in the Dal-Tex Building was Dallas Uranium & Oil Company, a business to which Morty Freedman was also affiliated. Abe Zapruder, a Jewish dress manufacturer, was one of Morty Freedman's business partners in the Dal-Tex Building. Note that Abe Zapruder filmed the John F Kennedy Assassination, creating the famous Zapruder Film, which he later auctioned off at a handsome price to a senior executive at Time Life Magazine, Charles Douglas Jackson, whose CIA connections have now been proven.
