I've watched the scenes where the flashes are shown. Folks, the government hasn't a shred of credibility on this topic. The flashes are gunfire, plain and simple.
Consider a helicopter flying over the scene. Glass would have to been lined up in a neat little row, so that as the helicopter moved, the flashes would appear at the proper rate to mimic the muzzle flashes. Even then the flashes would have to move along the line of broken glass. When glass breaks, it doesn't align in a straight row. It rests in a patch of broken shards. Why then don't the reflections appear to jump around? The broken glass scenario is nonsense.
If I remember correctly, there was more than one location where gunfire could be seen. In neither instance does the "reflaction" theory hold up under scrutiny. In neither instance does the flashes resemble reflections that jump around as in a patch of broken glass.
The juvenality, if there is such a word, of the federal government on this topic is mammoth. Nobody believes them. It would have been far easier to admit to their actions and deal with the heat, than forever forveit any claim to honesty on the topic. Our federal government was guilty of mass murder IMO.
