Supreme Court ruling on drug mule conviction

The Supreme Court ruled in favor of a drug mule's conviction, stating that expert testimony from an HSI special agent did not violate federal evidentiary rules. The case involved Delilah Diaz, who was stopped at a U.S.-Mexico border entry with methamphetamine in her car. Despite Diaz's claim of being unaware of the drugs, the court upheld her conviction based on the agent's expert testimony.
