I haven't done the research you have, but distinctly remember at least one post after the big firefight during that time, remarking that there had been a big boom and no one said anything about it -- that we no longer got excited about just a few... I don't remember the time.
There was so much going on all night ("here" time) that a few isolated booms, more or less, weren't going to ring a lot of bells...
Also, we don't know the location WRT the cams, do we? The "residential area" might have been far enough off that it was only a dull rumble (the BBs go off after penetration).
Keep hope alive :-).
