Three people were killed in last week's shootings in Tulsa, Okla.: Dannaer Fields, 49; William Allen, 31; and Bobby Clark, 54. Two others were wounded in the shootings. All of them were shot — apparently at random — in the predominantly black neighborhood of Northgate in northern Tulsa.

"I came through there and I realized it was my brother laying in the street," Clark says. "They shot him under the armpit, and I think it hit his heart."

The Philadelphia Police Department is adding a new tool to its crime-fighting arsenal — Twitter. Supporters say the real-time information-sharing could help police build a stronger rapport with residents and better protect them.

West Philadelphia resident Mike Van Helder remembers when police knocked down his neighbor's door at 6 a.m. "There was shouting and loud noises and of course I didn't know what it was about," Van Helder recalls. "And them being my next door neighbors, I was understandably concerned."

Anders Behring Breivik, the Norwegian man who confessed to killing 77 people last July, was not criminally insane when he bombed a government building and gunned unarmed people down at a youth conference, according to two psychiatrists appointed by a court in Norway.

The new development comes days before Behring Breivik's trial is set to begin, on April 16.

The warmth and vigor of Bonnie Raitt's voice throughout her new album Slipstream, even when she's covering an oldie such as Gerry Rafferty's "Right Down the Line," is vital and fresh — urgent, even.
