There were only four other documented places a second gunman could have hidden.
1.Storm drain on Elm Street- This theory was proven to be false after a re-enactment was done. From the drain, there was no way a person in there would be able to see the President, much less have a clean shot.
2. North end of the bridge the limo was to pass under- This theory was disproven because arieal shots of Dealy Plaza moments after the shots were fired showed the area empty, with no access to storm drains or areas of concealment.
3. South end of the same bridge- This theory was proven false due to the presence of railroad workers in the area, none of which saw anyone suspicious, as they all knew each other.
4. The grassy knoll- This theroy, while valid, is still a long shot. The area the shooter was said to be in did not offer a clean shot at the motorcade, as the line of sight to Elm Street was blocked my numerous trees and people. The only window of oppertunity to fire at the president was only about a second long, and the place where the fatal shot struck the president did not support the grassy knoll theory.
It was proven the Carcano rifle Oswald used, while an inferior weapon, would be capible of a fatal shot. Though the rifle had a 23% chance of misfiring, Oswald would have been able to fire three rounds in under 8 seconds.
There also would have been plenty of time for Oswald to dismount, hide the rifle, and decend to the second floor cafeteria before the police entered the building.
Oswald was fingered for shooting Kennedy after he was arrested for the murder of a police officer. The rifle found at the Depository was Oswald's, therefore he was charged with the murder of the president.
The only thing unexplained was Ruby. He said he shot Oswald out of anger for the president, and for Jackie. Had it been a conspirecy, he most likely would have not rotted in jail. His credentials were all in order and nothing identified him with the Mafia or the White House.
