You fail to make a point here but I assume you are implying this is bad.

The question would then be, why is it bad? Would you accept that it is permissable to film a public scene in general? If so, and this is not a rhetorical question, what is the difference?

That difference may cross a line of privacy when considering what a reasonably assumable degree of scrutiny is expected in public.

That is not a simple question and the law may have a different answer to public opinion which may be different again to what is best for society.
