In the context in which you write, you are indeed correct, I have misunderstood D SQDRN 97th IOTC and I apologise to him for that.
That said, and within revised context, s78 of the Police and Criminal Evidence Act 1984 is still very clear.
Of course, the purported Go Pro 'evidence' is minuet should any case need answering, and I shall now refrain from mentioning it further.
