I watch quite a lot of TV news – News 24, Sky news etc. Although the majority of reporters are white, there have been, over the years, quite a number of non-white reporters and news readers. I don’t see any bias, hopefully whatever race a person is they will report what they see truthfully.
As for matching the ethnicity of the reporter to the people he/she is reporting on, that would be silly – a kind of apartheid, almost. However, for in-depth investigations, ethnic matching might be worthwhile, and is probably done already.
