Who would want to be a cop in America? It’s open season on anyone who wears a badge, so no wonder recruitment is down, retirements are up and the streets grow ever more violent. By swallowing the false narrative of systemic racism, we have demonized and criminalized police while turning criminals into civil-rights martyrs. This won’t end well. By all accounts, the police shooting of a black man, Daunte Wright, Sunday during a traffic stop in the Minneapolis suburb of Brooklyn Center was a stupid, horrible accident. But it’s not racism. The fact that it happened just 10 miles from where a former police officer, Derek Chauvin, is standing trial for the killing of George Floyd just makes the calamity unfathomably worse. The threat of extreme violence if Chauvin is acquitted already had the country on tenterhooks. But Wright’s death ensured the riots and looting came early. You would think, at such a time, that our nation’s leaders would find a way of lowering the temperature. But no. Former President Barack Obama, who could wield more influence for good than anyone, did the worst possible thing.
