Sorry, I thought we were talking about evidence of murder, not evidence of carrying a gun down the street.
That unlucky Oswald, he flees the building from which many eyewitnesses said shots were fired from, and ends up walking down the street away from a just occurred murder while removing shells and carrying a gun?
IIRC the first Dallas Police shooting since 1961 just happens when Oswald was walking close by, while carrying his gun, geez what are the chances?
