The incident nonetheless highlights the increasingly polarising nature of the controversy surrounding Martin's death.
The 17-year-old, who was shot a month ago, was remembered during protests in Los Angeles, Washington, Chicago, New York and several other American cities over the weekend.
Demonstrators wore hooded tops and carried bags of Skittles, the brand of confectionery Martin was carrying during his fatal journey from a local convenience store to the home of his father's girlfriend, in a community called The Retreat at Twin Lakes.
Supporters of Zimmerman, who claims to have killed Martin in self-defence, began lobbying on his behalf. Joe Oliver, a "family friend" who appeared on ABC yesterday, said that he "couldn't stop crying" about the incident and is now in fear of his life.
Oliver, who is mixed-race, was accompanied by Craig Sonner, Zimmerman's lawyer. Both men vigorously denied that their friend, who was initially described as a "white male" by police but claims (despite his appearance and surname) to be Hispanic, is racist. Records show that Zimmerman had called emergency services almost 50 times in the past year to report suspicious activity in his neighbourhood. In most recorded instances, he identified the alleged "suspects" as young black males.
Shortly before Martin's death, Zimmerman decided to pursue him, against the advice of a 911 operator. On a tape recording of his telephone call to police, he complains, "these arseholes, they always get away". Then he appears to utter the slur "f***ing coons". Oliver was played an enhanced recording of the call by ABC, but claimed that Zimmerman was instead saying "f***ing goons". He insisted that "goon is a term of endearment in the high schools these days". He then alleged that a screaming man, who can be heard in the background of other 911 calls made to Sanford police on the day, sounded like Zimmerman. Martin's parents have previously identified the distressed man as their son.
Sonner used the ABC interview to claim that photographs of Zimmerman and Martin have given a misleading impression of the relative sizes of the two. Martin was taller than his killer, he said.
Zimmerman remains in hiding. Local police, who failed to arrest Zimmerman, arrested a man for sending threatening emails to Bill Lee, Sanford's former police chief. Lee decided to step down "temporarily" last week while officials review the case to establish whether Zimmerman should face charges.
