The murder of #GeorgeFloyd at the hands of a policeman unleashed a wave of protest across the United States. He wasn't the first unarmed Black man or woman to be murdered by an officer using unwarranted deadly force (there are about 100 per year). Nor is it the first time that we've seen mass protests across the U.S. in response to racial injustice. I've witnessed such events repeatedly in my lifetime, but this time it feels different.
