Police are still investigating whether the Tulsa shootings were racially motivated. We do know some of Tulsa's history. It has a difficult history of race relations, including a riot in 1921 that left scores, if not hundreds, of people dead.
Scott Ellsworth has studied that event closely. He's a Tulsa native who now teaches African-American history at the University of Michigan. He's on the line from Michigan Radio.
This is a story about what can happen when no one is looking. For the patients at Universal Pain Management, a medical clinic in northern Los Angeles County, Dr. Francis Riegler is always looking.
Riegler huddles with the clinic's nurse practitioner over a computer printout. The one-page report from the state's drug-tracking system shows that a patient was on the hunt for more Vicodin, a powerful pain reliever that he was already getting from Riegler's clinic.
The recession brought widespread unemployment across the U.S., but it also prompted a spike in the number of freelance or independent workers.
More than 30 percent of the nation's workers now work on their own, and the research firm IDC projects the number of nontraditional office workers — telecommuters, freelancers and contractors — will reach 1.3 billion worldwide by 2015.
In Greece, more than 21 percent of the working-age population is jobless. For Greeks under age 25, the rate is more than double that.
Some young Greeks are frightened that the economy, now in free fall, will take years to recover, so they're leaving for jobs abroad. A few entrepreneurs, however, are trying to start businesses during the worst recession in decades.
A magnet for these young entrepreneurs is CoLab, a business incubator in a weathered building near the Athens Cathedral in the city center. CoLab opened in 2009, with just one occupant — a Spanish travel writer.
