I have recently asked a question about a claim made by infosec.SE users which is, in simple words, "FBI can unlock an iPhone without Apple helping". This question was closed a a duplicate of this one, which references the initial claim as proof. So in the end, the claim made by infosec.SE users is effectively supported by itself.
I can see only two resolutions of this logical fallacy:
- either "FBI can do X" is considered common knowledge. In that case, sorry for wasting everybody's time.
- or, aswers on infosec.SE constitute a proof for Snowden's tweet, but can themselves be questioned as a claim. In that case, why is my question a duplicate?
