In Parker v. State, 248 Ga. App. 748, 749-750 (2) (548 SE2d 634) (2001), the trial court judge gave the jury an illustration about what constitutes evidence in the case. 248 Ga. App. at 749-750 (2). The judge warned the jury about how attorneys sometime use a "yellow rose" technique, in which an attorney repeatedly cross-examines witnesses about whether they saw yellow roses at the scene of the incident, even though the roses never existed and were completely fabricated by the attorney. Id. Due to the attorney's incessant questioning, however, some of the jurors become convinced that the roses were there, "even though there hasn't been one single smidgen of testimony to that effect from the witness stand." Id. at 750 (2).
