Millions of Americans have responded to the horrific mass shooting at Robb Elementary School in Uvalde with wrenching and public displays of anger, sadness and rage against the nation’s broken political system. This latest tragedy comes a little more than one week after 10 people were killed in a racist hate crime that purposefully targeted Buffalo’s Black community. The massacre in Uvalde coincided, almost to the day, with the second anniversary of George Floyd’s murder.
