I don't believe I suggested that it is the job of a sleuther to find evidence in an investigation instead of LE. I never said that.
I said until evidence is presented to the contrary, I cannot 100% think that BL killed GP. As you rightly point out, if this goes to trial, the evidence will be revealed at that stage. This is why I said the evidence as it stands is not sufficient for me. I'm open minded and if further, more concrete evidence is produced then I'm more than willing to fully believe that BL is guilty.
Additionally, I don't believe I've dismantled any facts to suit my own personal narrative.
Finally, you say "None of us here can convict him of murder based on not knowing all the facts of evidence that the FBI has". I think you'll find that plenty of people here have already figuratively 'hung, drawn, and quartered' Brian Laundrie, and have 100% convicted him in their own minds, regardless of the facts and evidence presented.
I won't apologise for keeping an open mind - I think it's what sleuthing is all about.
