I was charged with one count of sale of sch.II(morphine),hired a $7,500 lawyer,went to court,on my plea date,i already got my discovery,but they only sent the written part ,no audio,so i stood up in front of judge and asked him if i could hear the tape,he said talk to my lawyer,my lawyer said it is within the d.a.'s rights, to withhold the tape, unless i refuse the plea agreement,is this true?
