Core Values

Jordan Edwards spent his last moments in a car driven by his 16-year-old brother in a Dallas suburb. The teens in the car — Jordan, his two brothers and two friends — had no weapons, and they were not drunk. None of them has been charged with any crime.

At first, Balch Springs Police Department Chief Jonathan Haber claimed that one of his officers, later identified as Roy Oliver, fired at the teens’ car because it was backing down the street in an “aggressive manner” toward officers called to break up a teen party.

Hours later, the police chief walked that story back, saying body camera footage showed the car driving away when the officer raised his rifle and began shooting.

“After reviewing the video,” Haber said, “I don’t believe that (the shooting) met our core values.”

The Dallas County medical examiner has ruled Jordan’s death a homicide. Cause of death: gunshot wound to the head. The police officer has been fired. We await further news about what happens next.

Cognitive Taxes

In a series of experiments run by researchers at Princeton, Harvard, and the University of Warwick, low-income people who were primed to think about financial problems performed poorly on a series of cognition tests, saddled with a mental load that was the equivalent of losing an entire night’s sleep. Put another way, the condition of poverty imposed a mental burden akin to losing 13 IQ points, or comparable to the cognitive difference that’s been observed between chronic alcoholics and normal adults.
