Hmm, I really hope you are right. My thinking on this, however, is different and based in part on the opinions of the criminologist/behavioral analyst seen in this video from HLN about the Delphi murders. This was the "extra" Youtube special that HLN showed in conjunction with their two part episodes on Delphi earlier this year:
Watch what the expert has to say at around minute 3, minute 9 and minute 42. At each point she talks about the importance of keeping information (I would assume,
accurate information) about this case in the forefront of media to assist in solving it. She makes the point that many cases are solved because people realize, years later, that
they know something that they did not realize they knew.
She also talks about the "pall of denial" and how that impacts people's ability to come forward to LE with important, definitive information. The factor that tips the scales for them is likely not the reward but the mental state of coming to the realization that they can no longer deny what they know.
If opinions stated as facts and rumors are allowed to take hold on message boards like WS and other sources of information for the public, how might this contribute to the "pall of denial" that prevents some crimes from being solved, or being solved until years later? Just food for thought.
