For the record, at the time he attended the lineup, Brennan did pick Oswald as most resembling the man (of all the lineup "suspects") who he saw in the window.
While this may not be a proof positive identification, it is also inaccurate to state that Brennan did not identify Oswald in the lineup.
Not inaccurate at all. The one of the four who "most resembled" who he saw is NOT the same as identifying Oswald as the one he saw.
Besides, that is specifically
not what you're supposed to be instructed to do in a lineup.
