Among the newly-released tapes of 911 calls made before and after murder of Trayvon Martin, one stands out: a recording of the call made by the shooter, George Zimmerman. The 28-year-old Neighborhood Watch captain of a Sanford, Florida gated community can be heard voicing his suspicions about the 17-year-old Black teen. In one call, you can hear him actively pursuing Martin before the deadly shooting.

“Are you following him,” an emergency dispatcher asks after Zimmerman describes Trayvon as a “Black male who was acting suspiciously.” Zimmerman responds, “Yeah.” The dispatcher follows with saying, “OK, you don’t need to do that.” Tapes of that call, and several made by frantic neighbors who heard shots fired, were released by WESH in Orlando. In other recordings, pleading and cries for help are heard, falling silent after the sound of gunfire. Martin, who had no criminal record, was leaving a convenience store carrying nothing but a bag of Skittles, money, and a can of iced tea. Zimmerman is even heard on tape complaining to the dispatcher, “These a–holes always get away.”

With the 911 tapes being released, what is taking the authorities so long to arrest this murderer?
