In defense-witness exchange in a US murder trial, the defense shapes the killed Trayvon Martin’s use of the term creepy-ass cracker as proof of racially motivated aggression towards their ‘white’ client, immoral within post-racial America. The defense’s symbolic control claim over the term’s meaning indicates relative unmarkedness of Standard AE and whiteness in current US judicial systems and society, and his use of pauses, hyper-articulated STAE, and symbolic deictic terms discursively and linguistically isolate Martin’s and witness Jeantel’s community from directive white courtroom practices.
