I do not agree that privacy works this way. For me, it's not invaded once the peeping Tom shows up, it was degraded when there was opportunity for him to peek.

I do not agree that privacy works this way. For me, it's not invaded once the peeping Tom shows up, it was degraded when there was opportunity for him to peek. Footage might be destroyed, but one can never be certain that there aren't copies elsewhere. It may seem secure, but how can I be certain that there won't be some future exploit that exposes it to even more people (never mind those who already have access). I think the principle here is that my privacy exists not because you and others promise not to invade it, but only when I can secure you from doing so. Once the cameras are policy, no one who works there will be able to do that for themselves.
