Not once have they caught Westerfield in a lie. Not true. There are several, including lies of omission, in his interview with Det. Redden, for example.
In fact I've an idea regarding an interesting detail I didn't know until today.
I'm off to research it a bit.
Westerfield has NOT testified under oath.
The police interview is totally one sided and not controlled. You can't say he left anything out, because he was constantly interrupted and you only heard 5% of it.
Even the part you heard was highly edited per Dusek.
