The release of this footage is a key moment early in the case, as it reveals that a 911 dispatcher instructed Zimmerman not to follow Martin. With the story just having gone national, the revelation leads to cries for Zimmerman to be charged.

Seven 911 calls from the night George Zimmerman shot Trayvon Martin are released. Each of the calls features a gunshot and bone-chilling screams. NBC  later finds itself in hot water after the Today Show plays an edited Zimmerman 911 call that makes it sound as if he only pursued Martin because of his race. After launching an internal investigation, NBC is forced to apologize and fire the producer who edited the call.
