Impeaching the D-W
Miranda defective statements can be admitted for purposes of impeaching a Ds credibility on cross if such statements are made voluntarily
Limitation on impeaching D
If a confession is involuntary as opposed to merely Miranda defective then it cannot be admitted for any purposes including impeachment purposes
Pre-arrest or Postarrest pre-miranda silence
Can be used for impeachment purposes only
If D waives his rights then is silent
He can still be impeached though his silence but only on material omissions
A statement unconstitutionally obtained that identifies a suspect and then the person identified in the statement is interrogated and from that interrogation you get constitutional statements
if the initial confession that led to the identification was a product of coercion and not voluntary then cannot use identified persons statements (but can use the fruits if the initial confession was voluntary)
A statement unconstitutionally obtained that leads to physical evidence
Exclusionary rule does not bar the physical fruits from a non-Miranda confession because physical evidence is non-testimonial
Factor for allowing subsequent confessions (to non-miranda confessions) to come in
Attenuation (including break in time and different counsel)
Content of the subsequent confession
When you read minister Miranda and get a second statement/confession the subsequent statement is admissible if it is about different activity or a separate crime (identical portions won't come in)
Emergency Exception
Overriding considerations of public safety justify an officers failure to provide Miranda warnings and that unwarranted confession is admissible in the People's case in chief (like kidnappings, terrorism or safety of police officer)
