xtended footage has now been uploaded by Dave / @realDJStew724:
His closing remark:
Looks like it was just Crooks shooting after all.
Don't see how you can draw that conclusion.
So I suppose a more precise conclusion is: it was just Crooks shooting... from that building.
One can now see the extent of how many police were drawn in around the building before shots were fired, yet other than the shell casings, there is no evidence of him actually firing (who saw - no one as of yet). If might be well assumed he did fire at least 5 rounds, a probability, yet the first three perhaps not. Shell casings were said to be 5 and then added upon to be an additional 3, for 8 shells casings over all, which is suppose to be case closed move along.
The sound is much clearer from this video, yet there is a still a difference between shots 1, 2 and 3 to the next 5 staccato burst rounds.
