You sound quite certain here, how come?
A letter filed by Assistant US Attorneys Jason Swergold and Maurene Comey said "the footage contained on the preserved video was for the correct date and time, but captured a different tier than the one where Cell-1 was located", New York City media report.
"The requested video no longer exists on the backup system and has not since at least August 2019 as a result of technical errors."
And from NPR:
After first reporting that the video had been preserved, prosecutors told the court that further investigation shows "the MCC inadvertently preserved video from the wrong tier within the MCC."
As a result, the pertinent video "no longer exists," prosecutors wrote.
Are you saying this is untrue? Or is this an "akshually it was a data entry error not a malfunction" type of thing?
