Yesterday, our colleague Renee Montagne met with the American general who commands coalition forces in Afghanistan.

Today, Rick Bounds is a 58-year-old triathlete, with four competitions and a 100-mile bike ride to his credit.

He was given eight months to live and told that his chances of getting organs were slim.

'No Hope'

Sales of guns and ammunition rose after President Obama took office in 2008, and they went through the roof starting late last year, when a school shooting led to a push for new gun control measures. That's led to a prolonged ammunition shortage, even with manufacturers running at full capacity.

President Obama had a reputation when he took office as a liberal former constitutional lawyer who had condemned Bush-era national security policies.

But he has proven to be even tougher than President George W. Bush on prosecuting national security leaks. The seizure of Associated Press phone records is just the latest example.

The candidates have spent a record amount of money. They've stumped hard in a city that isn't easy to campaign in — 470 square miles sliced up into neighborhoods divided by a web of freeways.

Yet despite nearly $20 million in spending in the March primary alone, turnout is expected to be low next Tuesday in Los Angeles when voters go to the polls to pick a new mayor to replace the term-limited Antonio Villaraigosa.

As a result, City Councilman Eric Garcetti and his opponent, City Controller Wendy Greuel, are engaged in an all-out blitz for votes across the sprawling city.

In the Western stereotype, Buddhists are meditating pacifists who strive to keep their distance from worldly passions. But last month, more than 40 people were killed in fighting between Buddhists and Muslims in the central Burmese town of Meiktila. Witnesses say some Buddhist monks joined in the violence, while others tried to stop it.

One prominent monk in particular has been blamed for being behind it.
