I am well aware of this phenomenom but I don't get the same sense in this case. I know all about eliciting false confessions.
However, she lied in her statements.
See it's one thing to say she just started making things up to "give them what they wanted to hear" in order to get out of a room, it's another thing to start changing your story right off the bat.
I'm a novice to all this and don't really take a position one way or the other, but I don't think her "coerced" statement is similar to other cases of coerced statements.
She started off with a lie. I watch a lot of 48 hours Mystery online, and the pattern of her behavior is very similar to the criminals that they have caught that actually did it. She starts off lying. Once they can tell her story is not adding up, (or for some experienced interrogators) then they begin to apply pressure.
One thing that is interesting to me is that she started off with a lot of different versions and stories. So then to say she made up the confession doesn't make a lot of sense.
Again I don't know too much about this case so forgive me if this has been debunked. I just found an article here that lists the lies. I'll paste it so you can take a look.
But the one lie that stood out to me is that she said she wasn't home when she was. Also that the police showed up because Kercher's cell phones had been retrieved and also why she didn't call the police immediately when she saw a break in and blood in the apartment?
