I am a little confused as to why these guys are demonstrating. There seems to be no obvious catalyst - i.e. in response to a recent example of police racial prejudice. Also isn't BLM an American organisation? It just seems like they are making a point for the sake of it rather than getting themselves heard in a more constructive way. Also, IMO all lives matter, so equality should be the same whatever race you are. I can't really see how are they going to do much more than annoy people by blocking roads.
