The British version of the Miranda warning
"You do not have to say anything, but it may harm your defence if you do not mention when questioned something which you later rely on in court. Anything you do say may be given in evidence."
I can't make sense of that first sentence. What's the effect, if someone later remembers something they forgot to mention when they were first questioned? Is it inadmissible?
I've only watched the first two episodes -- haven't seen any court scenes -- so maybe this will make more sense later.
It just seems odd.
