Self-defense or murder?
That's the question at the heart of the trial of George Zimmerman, a neighborhood watch volunteer who killed 17-year-old Trayvon Martin.
Monday marks the start of jury selection in Seminole County, Florida, where Martin was fatally shot on February 26, 2012. (...)
An initial decision not to pursue charges against Zimmerman led to the dismissal of the town's police chief and the appointment of a special prosecutor, who accused the neighborhood watch volunteer of unjustly profiling and killing Martin.
Zimmerman now faces a second-degree murder charge in Martin's death. He has pleaded not guilty and is currently free on $1 million bond.
