I'm sorry but I seem to be missing something here. Are you faulting the BBC for not showing the pictures of people carrying hateful and violence encouraging signs?
What exactly are you saying with regard to the images and the BBC?
I believe I already know, but you somehow failed to make any point in your article with regard to this.
The article obviously depicts it as a peaceful demonstration and didn't show any of these pictures. As far as I know there was no violence at that demonstration and there were obviously some extremists there as evidenced by the signs, so are you saying the BBC flat out lied or simply chose to misrepresent the demonstration?
Or perhaps you are simply leaving it for the reader to make their own conclusion?
