SANFORD, FL - MARCH 28:  The Retreat at Twin Lakes gated community, where Trayvon Martin was shot and killed by George Michael Zimmerman while on neighborhood watch patrol, is seen through a hole in a security gate on March 28, 2012 in Sanford, Florida. Florida ranks second behind California in the number of gated communities in the nation. Marketed as secure status enclaves, opponents argue that walls and gates foster a fortress-like mentality with very little pedestrian activity that doesn’t necessarily reduce crime.
