I would point out first that when you say cameras appeared on the premises immediately, it was about two and a half hours after the operation had started. Personally, I wouldn't call that “immediate”.
As to what will be done with the images that were taken by those who took them, at this point in time I must say it's highly speculative. I'm not familiar with how these things may or may not be used, whether it would be appropriate or not appropriate, or what sort of remedy would fall depending on whether they are used, how they are used, or for what purpose they are used. I cannot comment any further on this matter.
