WTC7

The above image consists of two shots of WTC7 taken on 9/11. The Left photo is attributed to the NYPD, and is used by NIST as corroboration for eyewitness testimony that suggests that debris from the collapse of the towers caused a specific amount of damage to WTC7. The photo on the Right is by Aman Zafar. The discrepancy is obvious, Zafar's photo does not confirm the visual data in the NYPD photo.

Researchers should petition NIST for provenance on this photo. If the photo was taken with a digital camera as other helicopter shots from 9/11 were, then Exif data should be embedded in the file that will reveal a time-stamp. The original file should also reflect what we see in the NIST drafts, and not bear evidence of tampering in Photoshop or other image editing software. A separate inquiry to the NYPD probably wouldn't hurt. (If you have a connection there, use it.)
