Cold blooded murder of Trayvon a "culmination" of Zimmerman's "mounting concern and frustration" [View all]

For the first time last week, we heard Zimmerman, in his own words, explain to police what he said was going through his mind after he spotted the teen in his Sanford, Fla., neighborhood Feb. 26.
His defense team released recorded interviews Thursday in which police question Zimmerman in the days after the shooting, before the controversial case drew any substantial media attention or public outcry, and before Zimmerman had a lawyer.
One thing is clear: To Zimmerman, it was not an isolated incident. It was the culmination of mounting concern and frustration about crime in the subdivision where he was Neighborhood Watch captain.
Prosecutors say the unarmed 17-year-old from Miami Gardens, Fla., was an innocent victim of profiling. Zimmerman, charged with second-degree murder, says he fired during a struggle for his life.
