Really good story here.
Very long, but explains why he might have followed Saint Trayvon despite being advised not to.
On February 2, 2012, Zimmerman placed a call to Sanford police after spotting a young black man he recognized peering into the windows of a neighbor's empty home, according to several friends and neighbors.

"I don't know what he's doing. I don't want to approach him, personally," Zimmerman said in the call, which was recorded. The dispatcher advised him that a patrol car was on the way. By the time police arrived, according to the dispatch report, the suspect had fled.

On February 6, the home of another Twin Lakes resident, Tatiana Demeacis, was burglarized. Two roofers working directly across the street said they saw two African-American men lingering in the yard at the time of the break-in. A new laptop and some gold jewelry were stolen. One of the roofers called police the next day after spotting one of the suspects among a group of male teenagers, three black and one white, on bicycles.

Police found Demeacis's laptop in the backpack of 18-year-old Emmanuel Burgess, police reports show, and charged him with dealing in stolen property. Burgess was the same man Zimmerman had spotted on February 2.

Burgess had committed a series of burglaries on the other side of town in 2008 and 2009, pleaded guilty to several, and spent all of 2010 incarcerated in a juvenile facility, his attorney said. He is now in jail on parole violations.

Three days after Burgess was arrested, Zimmerman's grandmother was hospitalized for an infection, and the following week his father was also admitted for a heart condition. Zimmerman spent a number of those nights on a hospital room couch.

Ten days after his father was hospitalized, Zimmerman noticed another young man in the neighborhood, acting in a way he found familiar, so he made another call to police.

"We've had some break-ins in my neighborhood, and there's a real suspicious guy," Zimmerman said, as Trayvon Martin returned home from the store.

The last time Zimmerman had called police, to report Burgess, he followed protocol and waited for police to arrive. They were too late, and Burgess got away.

This time, Zimmerman was not so patient, and he disregarded police advice against pursuing Martin.

"These assholes," he muttered in an aside, "they always get away."

After the phone call ended, several minutes passed when the movements of Zimmerman and Martin remain a mystery.

Moments later, Martin lay dead with a bullet in his chest. http://www.reuters.com/article/2012/...83O18H20120425
