Was the assassination a conspiracy ?

Oswald was interrogated throughout the weekend, though no recordings or transcription were made. During an intended transfer to country facilities on Sunday morning the 24th, Oswald was shot and killed on live television in the basement of the Dallas police station.

Advocates of a blue -ribbon panel won the day, and on November 29 president Johnson signed Executive order 11130 creating a president's commission headed by supreme court chief justice earl warren.
The Warren Commission relied on the FBI and other agencies, particularly the CIA, secret service, and state dept. using a staff of lawyers but not field investigators.

Transcripts of executive sessions revealed problems with his approach, such as the commission's failure to investigate the allegations that Oswald was an FBI informant. The commission seeming thoroughness has been challenged by critics who have pointed out the many important witnesses never interviewed.

A small group of private citizens read not only the Warren report but also the 26 volumes of published testimony and evidence upon which it was supposedly based. What they found was a host of contrComposeadictions, implausibilities and stories which never  made it into the 888 page report.

Many witnesses had heard gun fire emanating from the grassy knoll to the right front of the motorcade,whereas Oswald was allegedly in a sixth floor window behind the president. The problems the Warren commission uncovered was that all secret service agents were accounted for and none were in that area.
