That’s the whole point, they don’t have to ever admit it, regardless of the publicity, short of hidden camera footage.

The huge problem is, that even when it’s damning enough that 99% of people call bullshit, their denial will continue to cause great pain and make it difficult for other people to get justice in the future.

In a perfect world they wouldn’t have committed the crimes in the first place, but it’s a relative scale, and having an uncontested documented case is a bigger win over a denial, than having a good apology is over a bad/non apology.
