. . . or they got that info from somebody besides Brennan.
Who would that be??..... Howard Brennan is the ONLY person who stepped forward immediately after the shooting at 12:30, and reported seeing a man aiming a rifle from a TSBD window. A few minutes later the cop called in and gave the description to the dispatcher....at 12:45 the dispatcher broadcast the description....
Rational thinking does come easily for you does it Johnny?
