Sure, I agree that it’s a stupid idea from an effort vs reward perspective. It’s at best unnecessary.
But your initial position was that it couldn’t be done without being easy to prove that it was a fabrication, and I think you’re wrong about that.
I think that they are more than capable of doing it in such a way that it’s wholly word-vs-word, with no forensic evidence pointing to it being doctored. And the idea that they would do that is outlandish enough that most reasonable people would assume the post was legitimate and that the “offender” was lying about it to try and deflect blame.
It’s the classic, "No, I didn’t post that list of porn search terms to my Twitter! I was hacked!! Totally somebody hacked me and did that. Wasn’t me at all!!” But in this case it’d be something that was a pretext for the government to arrest them.
Just because it’s generally possible for the bladder to rupture before the muscles give out, it’s certainly not impossible. A myriad of conditions or even just genetics can lead to a physically weaker bladder.
I think it’s a bit bold to say that absolutely 100%, no exceptions, that the muscles will always fail first. Even if that’s true 99.99% of the time, there’s just far to much variance in human bodies to rule it out, I would think.
