> The burden of proof is on you, making the claim that the FAA chief and the crash are connected. What's your evidence?
I did not make this claim. I’ll restate my position so we’re clear: I have no idea whether they’re connected.
> I'm advancing the null hypothesis, that they have nothing to do with each other.
This is still a claim which requires evidence.
> I also don't believe the Eagles winning the NFC Championship 2 days earlier has anything do with the crash -- are you expecting me to provide evidence for that as well?
In general, evidence is required for any claim, yes. But in this case, something like “The Philadelphia Eagles are a football team, without any responsibility over airline safety” is probably enough evidence.
