Outrage over the shooting death of Trayvon Martin spread across the country this week following the release of the recordings of 911 calls. Trayvon Martin was unarmed. He'd gone out to purchase candy. Thousands of people protested this week, donning hooded sweatshirts in solidarity with Trayvon Martin, who was wearing one when he was shot. Many called for the arrest of George Zimmerman, the neighborhood watch volunteer who says he shot the 17-year-old in self-defense.
This week, Mitt Romney and Rick Santorum got their secret service code names. Mr. Romney is Javelin. Mr. Santorum is Petrus. We asked Ian Chillag and Mike Danforth from the NPR podcast How to Do Everything to look into how secret service code names are assigned.
IAN CHILLAG, BYLINE: Presidents have been getting codenames all the way back to Harry Truman. The secret service called him General.
MIKE DANFORTH, BYLINE: Here's historian Michael Beschloss.
In a cave-like basement bursting with rickety old bicycles, tires and churning middle-schoolers, Daniel Furbish barks orders.
Close-cropped beard, pen behind his ear, Furbish is an artist-turned-teacher from a military family — creative and disciplined. He started his Nashville, Tenn., bike-building workshop as a summer experiment. He thought, "What if I take donated bike parts and teach kids to put them together?"
Students walked out of more than 30 Miami schools on Friday, some chanting "Justice for Trayvon," in a sign of solidarity with the 17-year-old black student who was killed by a neighborhood watch volunteer last month in Sanford, Fla.
Protesters numbered more than 1,000 at some schools, others fewer than 100. Some teachers and principals gave their tacit approval.
The first walkout was at Carol City High School, where Trayvon Martin was a student last year. Hundreds of his old schoolmates walked out in the middle of the school day.
