Seems Oswald did NOT try to hide the package, didn't even tape the open end closed, laid it on back seat in plain sight. Didnt go EARLIER in the night and hide it in the trunk. Waited till daylight,and carried along with one hand like it was an umbrella in bag, apparently not all concerned being seen carrying it, if crossing IN FRONT of the house past open windows with easy LOS to himself.
Managed to carry it really awkwardly too given that one sideways palm print "found" on the CE 142.
Was not really that concerned about getting the package into TSBD asap, after leaving BW Frazier in the car, cause Oswald just waited there by the fence, while Frazier stayed in the car, running the engine for another few minutes.
