Sean Murphy's research deserves more

[Tracy Riddle]

Looks like Sean's man is buttoning up his sleeves before getting back to work with the rest of them,
(or okay opening a can of... kick ass).

But, if Oswald is really that innocent about what's going on around him (doesn't even find it significant that the President has been shot outside his workplace), then he really should have been hanging around the TSBD for another half-hour to hour like a normal employee.

Oswald's actions after the assassination indicate someone who either played a minor role in the plot, or someone who has just realized that he's been set up (by people he knows) and he'd better escape.
