What's the opposite of 'drawing from incomplete evidence'?

I hate the power Facebook as a behemoth and a monolith holds and abuses. But when accusing, we should be fair. The statements cited as evidence are from a publication, not an offhand comment by a random person on Facebook with no regard to correctness or clarity. And even in that, there isn't clarity for what was being accused.

So, if pointing out a lack of clarity in an accusation is called nitpicking, so be it.
