You're fast! I edited my post before you resonded to it.
In the part I edited in my post, I added that that since most baby abductions are committed by those in or known to the family and there would be tons of justifiable various prints on things like light fixtures and doorknobs, it could simply be a prudent judgment call not to print everything. Possibly considering the factors specific to a baby abduction, there were good reasons that LE followed certain protocols that we don't know about. Since we don't know, I'm not assuming things were botched. I'm not questioning the right of others to make that assumption.
How do we know that LE didn't process points of egress? I think I missed something on that. I dont' remember LE saying that it wasn't part of the early search/processing and that it didn't occur while investigators were interviewing the parents during the initial response to the home. TIA!
