"If it was me" is not an argument.

"If it was me.... and the note said 10am, I'd be looking at the clock every 13 seconds!!!"

"If it was me, and my daughter disappeared, I would've run outside and screamed her name!!!"

"If it was me, I would've remembered every last detail about that day and been banging on the police doors!!!"

Well... it's not you. Guess what - people are different. They react to things differently and do things differently, especially in a high stress environment. People are notoriously terrible at predicting their own behavior. Especially when it comes to, I don't know, an unthinkable traumatic situation. Everyone also has unreliable memories, from the Ramseys to the police officers and in between. I don't know why people insist on these absurd "that's not what I would do!!" arguments. It has no bearing on facts of the case.
