Listening to the radio extract from 1958, I can straight away tell that there was a racial problem in Britain, and the fact that black and white people battled with each other, no one really won.
The man speaking talks about an 'invasion' by the black people and about the fights and riots that are breaking out because of the feelings black and white people had of each other. This speaker is representing the black people as if they were causing all the violence when really it was the white people being prejudice against the black people.
