It is illegal to post a whole lot of videos you might find pretty innocuous. A not insignificant portion of America has two party consent laws[1] that really restrict what you're able to record when it comes to private individuals. It has been pretty clearly decided highlighted that police do not enjoy this commonly held right[2] due to the sensitivity of their role but I really don't know if that same restriction extends to other public offices when acting in a non-public manner (i.e. the JCS) - I am really not familiar with the specific exceptions the above comment laid out so I won't comment on them... but it is illegal to post a whole bunch of different sorts of videos.

It’s illegal to record without consent in some states. Posting such a recording is problematic because it’s evidence of a crime, not a crime in and of itself. If it were, there would be cases of journalists posting transcripts from illegally recorded conversations, which isn’t happening.
