Prosecutors Legal Briefs had another excellent summary of the 3rd week
With so much D centric and frankly conspiratorial content around, it's nice to have some people who focus on procedure and trial tactics - mostly from a prosecutorial perspective, but they are also good at explaining what the defence are doing.
tldr;
In their opinion the confessions are brutal, and explain much of the defence strategy. The van is potentially a disaster and they don't find it credible that Wala somehow planted the idea. Brett actually jokes that if the prosecution really want to frame someone, please just do it with DNA and not with switched bullets etc. His point is, this increasingly vast conspiracy to set up innocent Rick doesn't make any sense if you think about it for 2 minutes.
Alice also notes a potential extra slip in RA's confessions - that he refers to branches, which is also what is in the evidence, whereas the defence has promoted 'sticks' - i can't recall if that was covered here.
They spend some time speculating that this might just be a very mundane case that has been seen many times before. A troubled man with a history of abuse in his own life, escalated to rape, and escalated to murder. The murders may not have been planned at all. Things got out of hand. According to them, this is an unfortunately common pathway, and much more likely that a satanic panic.
