The Case Against George Zimmerman
George Zimmerman spent the night in a Florida jail, on charges of second degree murder. More than six weeks after the self-appointed neighborhood watch captain admittedly shot and killed 17-year-old Trayvon Martin, the special prosecutor in the case announced the criminal charges in a news conference Wednesday night. Zimmerman maintains that he acted in self-defense, and many legal experts say prosecutors face a number of legal challenges in the courtroom. They must prove that Zimmerman intentionally killed Martin, who was unarmed, must show that Zimmerman's actions are not protected under Florida's "stand your ground law" and convince a judge in a preliminary hearing to proceed with the case. Guest host Jennifer Ludden talks with a prosecutor and defense attorney about what both sides in the case need to prove in court.

Are Cities Meaner?
After losing five bikes to thieves in New York City, Casey Neistat decided to conduct a social experiment. He set up a camera and pretended to steal his own bike several times around the city. He watched dozens of pedestrians walk past as he sawed through his bike lock on various streets with a hacksaw and power tools. In a recent piece for Salon.com, writer Will Doig cites this as just one example in his argument that cities are meaner places to live, though that's not because the people there lack in morals or values. Guest host Jennifer Ludden talks with Doig about the social research that explains why many urbanities do not assist or intervene.

When Couples Disagree About When To Retire
As more baby boomers prepare to retire, they're increasingly facing a complicated negotiation with their spouse: He wants to retire, but she doesn't. Or vice versa. By one estimate that appeared in the Wall Street Journal, "only about half of couples retire within two years of each other." And that can cause conflict. Many boomers live in dual-income families, and while each partner may have very specific ideas about when to retire — couples often avoid discussions about retirement altogether. Many men are older and hope to retire sooner, but their wives don't want them lying about the house all day. While many women are just reaching their professional peaks and have no interest in slowing down. Guest host Jennifer Ludden talks with freelance writer Kathleen Hughes and retirement coach Dorian Mintzer about how couples negotiate the timing of retirement.
