I tend to see it as folks filling in the blanks based on what has been said, what
hasn't been said, actions of LE, etc. Sure it's speculation but that's what we do here - discuss the case based on what we know, what we don't know, float some ideas, some speculation (usually based on both past cases where things were similar, and/or our own personal experiences in similar circumstances), and discuss whether or not it's a logical conclusion based on what little info we have.
What really strikes me, is how often folks here are utterly spot on with their assessments, based on SO little factual info at the time. There's some
really smart folks here.
