I really love the Court’s logic in this. “Look he didn’t testify that ALL Belgians is criminals. He just said that MOST Belgians is criminals. So it’s not, whatayacallit, discriminatory.”
I do not think it even qualifies as expert testimony.
Under Rule 702, expert testimony is *only* permitted if "the expert's . . . specialized knowledge will help the trier of fact to understand the evidence . . . ." Jurors don't need testimony from LEOs to understand drugs are valuable & fungible.
In his dissent, Justice Gorsuch makes the same point, more eloquently.
"Jurors are more than up to performing that task, and they hardly need the help of some clairvoyant."
