Supreme Court Decision Syllabus (SCOTUS Podcast)
Following what the Supreme Court is actually doing can be daunting. Reporting on the subject is often only done within the context of political narratives of the day -- and following the Court's decisions and reading every new case can be a non-starter. The purpose of this Podcast is to make it as easy as possible for members of the public to source information about what is happening at the Supreme Court. For that reason, we read every Opinion Syllabus without any commentary whatsoever. Further, there are no advertisements or sponsors. We call it "information sourcing," and we hope that the podcast is a useful resource for members of the public who want to understand the legal issues of the day, prospective law students who want to get to know legal language and understand good legal writing, and attorneys who can use the podcast to be better advocates for their clients.

Supreme Court Decision Syllabus (SCOTUS Podcast)
Diaz v. United States (Evidence / Expert Testimony)
Petitioner Delilah Diaz was stopped at a port of entry on the United States-Mexico border. Border patrol officers searched the car that Diaz was driving and found more than 54 pounds of methamphetamine hidden in the vehicle. Diaz was charged with importing methamphetamine in violation of 21 U. S. C. §§952 and 960, charges that required the Government to prove that Diaz “knowingly” transported drugs. In her defense, Diaz claimed not to know that the drugs were hidden in the car. To rebut Diaz’s claim, the Government planned to call Homeland Security Investigations Special Agent Andrew Flood as an expert witness to testify that drug traffickers generally do not entrust large quantities of drugs to people who are unaware they are transporting them. Diaz objected in a pretrial motion under Federal Rule of Evidence 704(b), which provides that “[i]n a criminal case, an expert witness must not state an opinion about whether the defendant did or did not have a mental state or condition that constitutes an element of the crime charged or of a defense.” The court ruled that Agent Flood could not testify in absolute terms about whether all couriers knowingly transport drugs, but could testify that most couriers know they are transporting drugs. At trial, Agent Flood testified that most couriers know that they are transporting drugs. The jury found Diaz guilty, and Diaz appealed, challenging Agent Flood’s testimony under Rule 704(b). The Court of Appeals held that because Agent Flood did not explicitly opine that Diaz knowingly transported methamphetamine, his testimony did not violate Rule 704(b).
Held: Expert testimony that “most people” in a group have a particular mental state is not an opinion about “the defendant” and thus does not violate Rule 704(b).
