really? Yes.
If your question is only around admissibility in criminal proceedings do you accept such video evidence could be admitted in civil proceedings?
In criminal proceedings, the test is not whether evidence shows criminal activity.
The test is more to do with relevance. And it may not be the prosecution that wants to admit the video evidence, it may be the defence.
Regarding the admissibility of evidence obtained unlawfully....there are several authorities. I suggest you go have a read.
