Seems to me the Tucson PD did a piss poor job with this one, other than the old caveat, "we can't release that", always the old mantra.
Don't they realize that human beings everywhere are invested emotionally when a child such as Isabelle goes missing without a trace?
Weighted against the desire to know details by the human beings everywhere who are invested emotionally, is the privacy of the people locally (including the family) who are invested emotionally as well. Alongside that privacy, is the security of the investigation.
In my own case, the release of information led to an internet witch hunt that was rife with libel, accusation, insult and idiocy. I weigh my own right to privacy above the curious minds of the general public. If the release of information can directly benefit the investigation (i.e. the parking lot surveillance video), then by all means that would trump my right to privacy. The same faux investigative journalist blogger that fabricated and misrepresented the information regarding me, has in the past prematurely released incorrect information about other cases that compromised investigations.
From what I've seen on the internet, any release of information is mostly twisted and misconstrued by most people to simply reinforce their existing ideas and suspicions. Websleuths is substantially more respectable in this regard than the rest of the internet community, but it is not immune.
The Celis family has been attacked by and large based simply on their demeanor in interviews and the general statement "I can't believe they aren't doing more". I can only assume that many people making that statement do not see them every day, do not know them, and are piecing that opinion together based on sparse information gleaned from brief television blurbs and internet chat rooms.
To those people I ask, "What is the Celis family doing?". The answer to that question is not "Nothing." Rather, to most people on the internet particularly, the answer is "I don't know." That doesn't equate to nothing.
With the current amount of information released, all that a logical person can say is "I do not know much about those people, how tragic that their daughter is missing.", rather than "They seem complicit". I seriously doubt that any information released by LE would positively impact the opinions of those people.
What I'm saying is, I personally hope that no further information is released, because I have first hand experience with the irresponsibility of the general public regarding that information. In fact, I absolutely wish less information had been released in the past. If that were the case, I would never know about this forum, never have had to spend the last year and a half defending myself, and less disinformation regarding the actual facts of the investigation would have been spread around to the general public.
I don't mean to come off aggressively, and I'm not actually directing this comment at you, necessarily. I simply read the appeal for more information to be released, and my immediate reaction to that is "Please, god, no."
With the 24 hour news cycle, it's a common thought that we deserve to know details as soon as they happen, in every instance. But the reality of life and society is that we don't have that right, and that is not always the best course of action. Information truly is power, and there is fallout in terms of real humans living real lives that are really impacted by the gossip and speculation that is spread around by national thirst for immediate details.
