Hello I need a 2 page summary to this question by tomorrow

Colorado v. Connelly ruled that a confession is admissible even if given under the influence of  

mental illness, as long as there is no police coercion.  Should the definition of “coercion” in  

interrogations be expanded to include psychological vulnerability and external pressures?  How  

do issues of pretrial detention and plea bargaining further complicate the voluntariness of  

confessions?
