Sorry, but I can see another line of consent here - how about when it is in the patients' best interests to do something for which they can't consent to at the time? I can't find the right words to explain it, nor (off the top of my head) do I know the section of the law this falls under. As I'm not sure maybe someone could clarify this....is a library/hospital/swimming pool/local government maintain highway all for public access and isn't there a law that allows any filming to be legal - like if someone stands on your street and takes a picture of you in your house, it's perfectly legal? Just some thoughts that spring to mind - I'm not saying that any are right before people start jumping down my throat!
