I am one of those who would be interested to know the behavior of the PsOI, especially as the discovery of the missing LS unfolded. Those observations are crucial to my speculating, although I realize that many people argue about the subjectivity and possible biases which present themselves when presuming to analyze an individual's overall behavior, including verbal and non verbal cues.
This investigation has not revealed any behavioral scenarios nor many direct quotes from people of interest. So I have had little to add to the discussion, despite the thought, that it is no wonder others can entertain so many possibilities for the disappearance of LS.
I do believe, however, despite the resolution of this case, that there are lessons to be taught. First, I hope that young people will take as much pride in staying in control of their faculties as they do in their academic achievements and personal appearance. And that they will begin to be dissuaded from chemical substance use. Professionals need to better understand the phenomena of both self medication and reckless behavior in our aspiring university culture. Indeed, many of these professionals are from this culture and many more will be. I am not certain that even within the dialogue in these threads, the general concensus is that unprescribed drugs are destructive. It seems that we are at best resigned that, although illegal and dangerous, drug usage is a rite of passage.
Secondly, it would serve us all well if members of society valued mutual concern and consideration, especially for their companions. Who of us, if first on the scene of an auto accident, house fire, discovery of a lost child in the mall or elderly person in distress, etc.. would fail to assist? Yet, how often might those very same citizens merely laugh at the stumbling intoxicated? Members of society need to be concerned for those under the influence. It is not as simple as just taking away their car keys.
Thirdly, depriving a family of the return of a human body must carry much stronger penalties. It ought to be unthinkable to believe that typical US university students would have such indifference and depravity toward not only human life, but for the human body! We bury pets in this country. Warring nations negotiate the return of human remains. As of today, miniscule remains of victims of 09/11/01 continue to be identified because families hope that even the tiniest trace of DNA will be recognized as their loved one.
It is time for awareness campaigns for all three of these lessons. IMO
