Use the right analysis order
Identify whether the suspect was in custody, then whether police words or conduct amounted to interrogation. If both are present, determine whether warnings were adequate and whether any waiver was knowing, intelligent, and voluntary. If rights were invoked, analyze the scope and effect of the invocation before considering later statements.
Common exam traps
Not every police question is interrogation, and not every stationhouse conversation is custody. Students also confuse Sixth Amendment counsel rules with Miranda counsel rules, or assume every Miranda violation requires suppression of all derivative evidence.
