One of the key guidelines that we teach in our courses and books is that the investigator should conceal details about the crime so that when a suspect confesses and provides those concealed details they can be used to corroborate the confession. If the investigator reveals the details about the crime in the interrogation through the use of leading questions, "She had a multi-colored shirt on, right?" (from the Rivera case) it eliminates the use of that information to corroborate the suspect's confession.

In their opinion overturning the conviction of Juan Rivera (based primarily on DNA evidence) in paragraph 44 of their opinion the court expresses their concern for the use of leading questions during the interrogation and the validity of the subsequent confession.
