An officer came to the house, county records show.
"Don't use pepper spray," he told the Zimmermans, according to a friend. "It'll take two or three seconds to take effect, but a quarter second for the dog to jump you," he said.
"Get a gun."
The homeowners association asked him to launch a neighborhood watch, and Zimmerman would begin to carry the Kel-Tec on his regular, dog-walking patrol - a violation of neighborhood watch guidelines but not a crime.
He was raised in a racially integrated household and himself has black roots through an Afro-Peruvian great-grandfather - the father of the maternal grandmother who helped raise him.
A criminal justice student who aspired to become a judge, Zimmerman also concerned himself with the safety of his neighbors after a series of break-ins committed by young African-American men.
Though civil rights demonstrators have argued Zimmerman should not have prejudged Martin, one black neighbor of the Zimmermans said recent history should be taken into account.
"Let's talk about the elephant in the room. I'm black, OK?" the woman said, declining to be identified because she anticipated backlash due to her race. She leaned in to look a reporter directly in the eyes. "There were black boys robbing houses in this neighborhood," she said. "That's why George was suspicious of Trayvon Martin."
"It was part of their upbringing to know that there are people in need, people more in need than themselves," said Post, a Peruvian immigrant who lived with the Zimmermans for a time.
Post recalls evening prayers before dinner in the ethnically diverse Zimmerman household, which included siblings Robert Jr., Grace, and Dawn. "It wasn't only white or only Hispanic or only black - it was mixed," she said.
Zimmerman's maternal grandmother, Cristina, who had lived with the Zimmermans since 1978, worked as a babysitter for years during Zimmerman's childhood. For several years she cared for two African-American girls who ate their meals at the Zimmerman house and went back and forth to school each day with the Zimmerman children.
They were part of the household for years, until they were old enough to be on their own," Post said.
In 2004, Zimmerman partnered with an African-American friend and opened up an Allstate insurance satellite office, Donnelly said.
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.
Police arrived just as the burglars - who had been trying to disconnect the couple's television - fled out a back door. Shellie Zimmerman saw a black male teen running through her backyard and reported it to police.
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.
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.
Please read the whole article, I tried to give the highlights. It defangs the whole GZ as racist argument, details how black teenagers were seen robbing the neighborhood several times, how GZ called the police before and the suspect got away before their arrival,(GZ tells the dispatcher "I don't want to approach him, personally."), and provides many other insights into his past. A police officer told him to get a gun. He partnered with a black guy to form his business, etc etc etc.....
