Street justice meets those who mess with LA bicyclists' ride

With more people getting to where they need to go via pedal-power, bike thefts have suddenly become a higher-profile crime.

Two Catholic high school students have a different story than the one told by the bike messengers. The teenagers say 20 men on bicycles robbed them -- took their backpacks, cell phones, and clothes -- and left them in their underwear. The bike messengers have a different take; there weren't nearly 20 of them, and they were simply giving the boys a comeuppance for participating in the rising wave of Los Angeles bike thefts -- up 29% in 2009 to almost 2,000 reported robberies.
