@Av8Chuck Well put sir!
In addition to the 'over people' issue, did the pilot also go to various rooftops to get each shot and maintain VLOS?
I would like to hope/think it's being done within the proper rules as folks who break them just make it harder for everyone else, but I agree with your assessment, it's difficult to confirm/deny 100% with the footage alone. A look at the black-box data would be the way to go to know for sure.
It's impressive footage, and if s/he is doing it by the book, it's even more impressive 😉
