I think the fear is that the TSA will deny having searched the phone and the complaintant will have not way of proving that they did.

Having the system have an ability to log all accesses after switching on get past this problem. As the logs will be proof the system was searched while not in your hands.

Does the system have such an ability?

I can't exactly go re-write iOS or Android (technically, I suppose I could do the latter) in order to add this feature.
