Backstory.

Here's a Reuters reporter who went down to Sanford, Florida and ferreted out the details of life in the Retreat at Twin Lakes neighborhood, pre-shooting.

Worth reading, especially if you live in an racially isolated, well protected area yourself, and are inclined to buy into the racial "hoodie-hunting" hype.

By the summer of 2011, Twin Lakes was experiencing a rash of burglaries and break-ins. Previously a family-friendly, first-time homeowner community, it was devastated by the recession that hit the Florida housing market, and transient renters began to occupy some of the 263 town houses in the complex. Vandalism and occasional drug activity were reported, and home values plunged. One resident who bought his home in 2006 for $250,000 said it was worth $80,000 today.

At least eight burglaries were reported within Twin Lakes in the 14 months prior to the Trayvon Martin shooting, according to the Sanford Police Department. Yet in a series of interviews, Twin Lakes residents said dozens of reports of attempted break-ins and would-be burglars casing homes had created an atmosphere of growing fear in the neighborhood.

In several of the incidents, witnesses identified the suspects to police as young black men. Twin Lakes is about 50 percent white, with an African-American and Hispanic population of about 20 percent each, roughly similar to the surrounding city of Sanford, according to U.S. Census data.

One morning in July 2011, a black teenager walked up to Zimmerman's front porch and stole a bicycle, neighbors told Reuters. A police report was taken, though the bicycle was not recovered.

But it was the August incursion into the home of Olivia Bertalan that really troubled the neighborhood, particularly Zimmerman. Shellie was home most days, taking online courses towards certification as a registered nurse.

On August 3, Bertalan was at home with her infant son while her husband, Michael, was at work. She watched from a downstairs window, she said, as two black men repeatedly rang her doorbell and then entered through a sliding door at the back of the house. She ran upstairs, locked herself inside the boy's bedroom, and called a police dispatcher, whispering frantically.

"I said, 'What am I supposed to do? I hear them coming up the stairs!'" she told Reuters. Bertalan tried to coo her crying child into silence and armed herself with a pair of rusty scissors.

Police arrived just as the burglars - who had been trying to disconnect the couple's television - fled out a back door.

Police had advised Bertalan to get a dog. She and her husband decided to move out instead, and left two days before the shooting.

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.
