At this stage, "implausible or fantastic justifications may (and probably will) be found to be pretexts for purposeful discrimination." Ibid. In that instance the issue comes down to whether the trial court finds the prosecutor's race-neutral explanations to be credible. Credibility can be measured by, among other factors, the prosecutor's demeanor; by how reasonable, or how improbable, the explanations are; and by whether the proffered rationale has some basis in accepted trial strategy.
