Regarding the "different lens". The LEO was not talking about the entire investigation really. He was talking only and specifically about LE's request regarding the southside parking lot.
approx 14:04
Reporter: Can you tell us if these are staged photos or if (unintelligible)?
DA: No further comment. Thank you.
Reporter: And on this photo, are you asking for anyone who was parked in this, this parking lot to call about (a bit unintelligible - every make of their car?) that was parked there?
Gates: Yes, that's what he was asking.
Detective: What I want to identify is the parents, it's more likely going to be parents who were attending the science fair. Sometimes in an investigation you look through it with a different lens than you do the very first day that it occurs. When you go back and you rethink of all the events and the information you have, you see bits and pieces of the investigation that you need clarification on. This is simply one of these events that we're looking for clarification on. The parents, the guests, the staff only in the area that I have depict (sic) in the photograph. We'd like them to call the tip line.
