The fact that BLM has led to police officers being murdered apparently does not concern Obama.
One of the great things about America is that individual citizens and groups of citizens can petition their government, can protest, can speak truth to power, and that is sometimes messy, and controversial. But because of that ability to protest and engaging free speech, America over time has gotten better. We’ve all benefited from that. The abolition movement was contentious. The effort for women to get the right to vote was contentious and messy. There were times when activists might have engaged in rhetoric that was overheated, and occasionally counter productive, but the point was to raise issues so that we as a society could grapple with them. The same was true with the civil rights movement and the union movement and the environmental movement and the anti-war movement during Vietnam. And I think what you’re seeing now is part of that long standing tradition.
