I'd like to point out that in your attempt to quote this interview, you leave out the part where Wiegert preludes his question with. "Alright, Im just gonna come out and ask ya..."
The reason this is important is because it shows Wiegert getting frustrated at not being able to have Brendan guess what it is they are looking for and in fact has now made some claims that are going to make it even harder for them to prove happened.
So again, we have Wiegert clearly, ABSOLUTELY clearly, telling BD what happened. And as we all know, this is after they tell BD they already know exactly what happened and he needs to just "be honest now" and tell the truth.
It's pretty clear that "be honest" is the key word for "no, wrong answer, try again". I don't know how you could read this confession and think it's legit. The other proven coerced confessions from the the Central Park 5 and the Memphis 3 were not even close to as obvious as this.
