I would think they were monitoring all communications. It would be naive to think anything less.
I read an article which said they had some 200 vehicles there, drones, and other assets. It is very likely that footage will never go public, if it was recorded.
However, when there are that many massed against you, there is only one reason: the take down.
Any privately obtained video may prove to be key to sorting out what happened there.
I am a former firefighter/EMS, and have long thought a drone with thermal imaging would be fantastic for looking for lost people, especially here in winter--if it is flying weather. Thermal differences, even with the hypothermic, are generally pretty high, and with the little ones, minutes count.
I have utter and complete faith and confidence the feds will lie their way out.
BTW, would thermal imaging pick up feds? Them being reptiles and all.
Sorry; but the FOIA covers those things that are NOT part of an 'ongoing' investigation.
Oh; and National Security.
