The application of AI in security is primarily needed to due to the enormity of the problem, not due to its ability to replace people. There simply isn't enough manpower or time to train experts and have them examine all the data. You can argue some of the data should not be examined at all for privacy reasons. But there are plenty of scenarios where privacy concerns won't hold. Such as comparing the security camera photo of a bank robber to mugshots.

The question of when it is reliable is an big one people have been working on a long time. For example in medicine the stakes are even higher. The problem is simply that recent technologies (deep learning) have taken a huge leap forward in performance, but a huge leap backwards when it comes to being able to assess confidence.
