Kate told Dave that both gates were shut?
2200: (approx): KM leaves table to check children in 5A. The patio gate is closed and the child gate is also probably closed.

I am sure David's references were to the front door.
He makes it perfectly clear in the quote I gave. "David Payne Quotes:
and again "I said well look how do you know that is the case, and err you know again I, I can't remember the exact words then, but I was very interested in finding what the state of the apartment was like when she'd got there to see who'd left err doors open or etcetera. And from my point of view you know the things that were, I think it was really pertinent to me was that there was two, there was two gates on the back entrance from that apartment. There's the gate which is immediately bring, you know brings you on to the err the road and then there was another child gate, that was at the top and I, you know,
and given the fact that the front door was shut".OK he maybe confirming the gates were shut , but Kate had already gone through those herself so
how did he confirm they were shut when Kate entered at the commencement of her check?
