Speaking of the Cobain case, people generally don't buy a shotgun to commit suicide. They buy a hand gun. Far easier to manage. Shotguns are for self-protection. You point them AWAY from yourself, as their scatter gun action makes them useful for a novice and just the sight and sound of them being cocked will scare burglars and prowlers away.
Also, no one high on opioids is going to want to hurt themselves. They are feeling too good for that. But someone strung out, in withdrawal might.
It's all common sense, but people throw that out the window when they hear lies repeated as "the official story". That's how brainwashed people have become to trust these "official stories".
But such folks are incredibly naive, with no knowledge of history, which repeats itself again and again, where such lies, initially believed by a gullible public, are later revealed to be total fabrications with no resemblance to truth.
For those interested in the truth of the Cobain case watching "Soaked in Bleach" (with an open mind) is a good place to start.
The documentary "Kurt and Courtney" also sheds some light on the matter.
And no, questioning the "official findings" does not make you an unhinged conspiracy theorist or a misogynist. Don't let the slings and arrows of the gatekeepers keep you away from seeking truth in any matter.
Be courageous and ignore the barking dogs who are just afraid of people not believing as they were trained to do.
They are just frightened children at heart.
