There's already been leaks such as a video of Hunter Biden smoking crack while receiving a footjob (edit: if this seems crude, I'm mentioning it as something that makes it very clear that the info is real) so unless you think it's a deepfake - or that they hacked it from his iCloud account and made up the story about the laptop repair shop - then you cannot deny the veracity of the story.
It's also been corroborated by people like the aforementioned Bobulinski. If this were truly a false story it would be trivial for the Biden campaign to deny the allegations.
The reason this story is not being reported is not because it's not "verifiable"; even ignoring that it is verifiable, the media had no trouble publishing the unverified story of Trump's tax returns, the unverified and now completely debunked Russia collusion hoax (if you're not read up on it, please don't reflexively downvote - with what we know today it is now certain that it was actually a manufactured hoax and not just an innocent misunderstanding), etc. So there is absolutely a double standard at play and it's very plain to see if you go look for it, but if you just stick to CNN and other mainstream media you will literally never see the full story (or even a fraction of it).
