According to LE, all he did was read 4 stories.
4 seems like a lot for anyone who has a kid and wears the facade of wanting them. That could be pretty hard for him to explain, because I don't think the defense can sell that he was absentmindedly curious about it, given the evidence we know. You never know what a jury will think, though. It might be a non issue to them. Things like those 4 looks, are a crap-shoot in my mind. They could be huge to a jury or a non-issue. I have to think if I were on that jury, I would be very concerned with his justification of looking at that.
