That's not actually true now is it Kev. Let's get the words right.
"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."
That says that you have the right to remain silent but you will be buggered if you do. Juries are allowed to draw an inference from the exercising of the right to silence.
A more 'on topic' example would be that you do NOT have the right to silence when accused of speeding. The camera takes a picture of *a car* that bears *a number plate* that is *listed as being in your keep*.
At what point is that evidence that *you*, the person, are guilty of any offence? The answer is it's not. So, you are either required to admit guilt or be summarily fined anyway.
The right to say nothing does not exist.
Justice my arse!
