The evening of the assassination, Oswald in custody accused of shooting Tippit. Also suspected of involvement in JFK assassination.
At that point Frazier, was known to be involved in getting Oswald a job at TSBD, drove him to work that morning, was his closest associate at TSBD, somehow left the scene after all employees who had been on 6th floor that morning were to be taken downtown for questioning. Was not located for many hours after the shooting. After being taken into custody, had his rifle confiscated and was called back to be given a polygraph after being told by Fritz to confess.
Sure, Frazier was shitting bricks at that stage and under the same circumstances, I would be too!
But the fact of the matter is, Frazier had no idea who else saw Oswald carry the long package into the depository, so obviously Frazier had to say that Oswald was carrying something long, even if imo Frazier
slightly underestimated the length, a guess is just a guess after all.
Who wants to be known as the guy who could have prevented a Presidential assassination because he didn't report an obviously suspicious package of about 35 inches?
