Facile platitudes, Mr. Lees. When Black Lives start to Matter then All Lives will indeed Matter:
"According to the most recent census data, there are nearly 160 million more white people in America than there are black people. White people make up roughly 62 percent of the U.S. population but only about 49 percent of those who are killed by police officers. African Americans, however, account for 24 percent of those fatally shot and killed by the police despite being just 13 percent of the U.S. population. As The Post noted in a new analysis published last week, that means black Americans are 2.5 times as likely as white Americans to be shot and killed by police officers."

The dirty, violent past still haunts the present.
