ABC 9/11 photos were finally released.
ABC finally got their hands on the photo after a freedom of information request was granted.
The photos show detailed imagery of the devastating attack on the World Trade Center. The attack killed 3,000 people on September 11, 2001.
Now we know that the National Institute of Standards and Technology keeps a lot of valuable information from the public as a part of its investigations process.
What other information does the NIST have that we don't know about?
