If there were some broken glass at that fixed location, you might well
expect to see multiple flashes as you move around it. This seems to be
what the VDS report describes.

VDS does not discuss this phenomenon, and I'm not sure why. It is
possible that the pattern is not as rhythmic and mechanical as some
have led us to believe. There could also be artifacts introduced in
the processing, copying and digitizing of the tape.

A certain amount of flicker is to be expected given that the reflective
surface is uneven, like broken glass. It probably wouldn't be at a
mechanical, even rate of repetition. I would like to see a graph which
shows the intensity of a flash over time, quantitatively. This would
help to determine whether the supposedly rhythmic pattern to the flashes
is actually as mechnical as has been suggested.

I don't think so. The pixels are very wide, either due to image
degradation or the behavior of the camera. From certain angles, this
makes the pixels appear to be linear and oriented toward the compound.
And for some reason the flashes are mostly seen from those angles.
Are there any instances where there are linear flashes which are in the
vertical direction on screen?

This is true. However we would need to see the test footage shot last
month to see whether this is actually a gunfire attribute. VDS used
this footage to establish their criteria. Maybe real gunfire does not
show such patterns.

I don't see how you could pick out shadows of gunshots (whatever that
means) given the crude resolution of the Waco video. VDS also talked
about stereo imagery. Is the FLIR a stereo camera? If so then again
they have more video information available than has been shown to the
public.

On the contrary, this is one of their biggest arguments in favor of
the sun reflection theory. In some cases there are multiple flashes
in fixed locations over a prolonged interval (many minutes) while the
visible light images show reflective material at that exact location.

I think if you look at the last figure in your flir02 URL above,
you see right there a strong argument for the sun reflection theory.
All the flash observations are clustered together in the left side of
the diagram. It's true, they aren't right on top of each other, but
you'd expect some variation due to uneven ground. This clustering is
hard to explain if it is gunfire.

(I believe you suggested that the building would have blocked view of the
"shooters" from other directions, but it didn't look to me like there
was that much obstruction. The camera was high overhead and looking
down at a steep angle.)

Keep in mind, too, that VDS also attributed a number of flashes to heat
from the hot underside of the tanks reflecting from debris on the ground.
