Alternatively, what happens if you are accused for a crime that you didn't commit during your "blackout period"?

While not a crime, i had some friends be very pissed off when i awoke from being blacked out drunk. To this day i do not know what faux pas i did...

Have you asked them? What sort of friends cannot broach the subject with you?

There's no reason to continue living in that situation if you can make amends or discover that they judged you in a faulty manner.

Seconded. They probably can’t remember. It’s a powerful thing to hold over somebody. If they ever fancy a chick who’s fancying you at a party for example, with that type of person something is sure to come out to put yhem above you. I’ve had some shitty drinking buddies and cut them all out of my life. Good riddance.

Life is for fucking up and growing, which requires feedback.

Not remembering committing a crime has never been a valid defence thus far and we have drugs that cause far more extreme behavioural changes besides just memory loss.
