Phillipe at end - Spoiler?

We're you doing something else while watching the movie? The cops think they have found evidence exonerating Baines in discovering the broken flower pot and the woman's shoe print that was made in the strewn dirt. They conclude that Mrs. Baines broke the pot and made the footprint while making her way to the precariously situated revolving (can't think of a better way to describe it) window to stare in at the bedroom where Baines' honey was and subsequently was thrown to her death (and not pushed in any way by Baines) when the window flipped after she leaned on it. After having it drilled into him by Julie that only telling the truth would help Baines Phillipe tries to tell the cops that it was he that broke the pot, and not Mrs. Baines, which indeed was the truth. He had done it earlier in the day when making his way to the window. But by that time he had lost all credibility with them (plus I think they were more than happy at that point to stick with the scenario that they had come up with--if you know what I mean). Plus, the woman's shoeprint Mrs. Baines made was ultimately more important than who broke the pot, even though we know she had made it earlier in the day. But in my book even if they had taken time to seriously consider what he was saying and decided to believe that he did break the pot there was still her footprint, which did somewhat dilute the suspenseful effect of him possibly unjustly incriminating Baines by "telling the truth."
