Hi Greg,
We need to explore make the case were there was 2 shooters.
The only 2nd shooter logical location is window 3 (as window 4 was closed during the shots), which is only 25ft further away from the podium.
Could you do a combined or 2 mappings where the 3rd window is origin for shots 1-3 & origin shots 4-8 is Crooks with muzzle at the ridge cap. ( were not concerned with shots 9 & 10 in this scenario)
Using trumps podium mike as the master sound track and shot 4 report less time for the sound to arrive as the zero point in time. From this point we can calculate & arrive at a ‘master time line’ for both crack and reports for shots 1-8.
This ‘master time line’ could represent either;
A) 3rd window is origin for shots 1-3 & origin shots 4-8 is Crooks with muzzle at the ridge cap.
B) Crooks is origin for shots 1-3 muzzle 2ft over the ridge cap & origin shots 4-8 is Crooks with muzzle at the ridge cap.
I have noticed a very strong agreement in timings of shots 4-8 for all sources, however crack & reports for shots 1-3, and time interval between 3 & 4 are all over the place. So only this part requires closer scrutiny.
There is a issue with the chain of custody with many of the sources.
For each of the other sources, it would not take long or much adjustment to alter/slide the sound track timings to point towards Crooks location. (crack & reports for shots 1-3, and time interval between 3 & 4)
Alternatively for each of the other sources, It would not take long or much adjustment to alter/slide the sound track timings to point towards the 3rd window location. (crack & reports for shots 1-3, and time interval between 3 & 4)
What would these timing adjustments values be?
I recall you posting that you massaged some of the values to get a better plot crossing alignments?
So instead of working towards 1 shooter result, work towards a 2 shooter outcome.
I noticed below that you were able to group shots 1-3 outside window 3, so with so refinement they may be even closer.
What I have not been able to obtain; is a xls table showing the crack & report timings used (indicating calculated or transcribed from wave forms) for all used sources for all 8 shots, for any of the analyses posted by anyone in the 3 or 4 studies posted on PP.
The Cruiser sound track should not be used, could the source tracks closer to the stage be picking up the broadcast sound from the speakers and not original?
Could the sound evidence point to a 2nd shooter from the third window or is this impossible? (i.e. like they were on top of the cell towers) I know this may take some time, but your all set up, experienced, and ironed out all the bugs.
