Your "Miranda Rights" are named after the U.S. Supreme Court case, Miranda v
Arizona, 384 US 436 (1966).

When Will The Police Read Me My Miranda Rights?
The police must advise suspects of their "Miranda Rights" - their right to remain
silent, their right to an attorney, and the right to an appointed attorney if they
are unable to afford counsel - prior to conducting a custodial interrogation. If a
suspect is not in police custody (i.e., "under arrest"), the police do not have to
warn him of his rights.

The police are very aware of when they have to read suspects their "Miranda
Rights." The police will frequently question a suspect, specifically telling the
suspect, "You are not under arrest, and are free to go. However, we would like
you to answer some questions." After the suspect voluntarily answers questions,
and sometimes if he refuses, he is arrested. The questioning, being voluntary and
non-custodial, is usually admissible. After arrest, the police may have no interest in
further questioning, and thus may not ever read the suspect his "Miranda Rights."

If The Police Don't Read Me My Rights, Can They Still Use My Statement?
Sometimes, a suspect will make voluntary statements after he is arrested. The
police do not have to warn suspects not to make voluntary statements, as long
as they do not deliberately try to elicit those statements through statements or
conduct. Sometimes, suspects will express their surprise at being caught by the
police, with statements to the effect of, "You got me." At other times, suspects
will try to justify their actions to the police after they are arrested, with
statements such as, "I don't know why I did it," or, "The drugs weren't mine - I
was carrying them for a friend." Those statements, if made spontaneously by a
suspect, will almost always be admissible in court. Additionally, if a statement leads
to the discovery of other evidence, even if the statement itself was taken in
violation of the Miranda ruling the police may be able to use that evidence.

Can My Silence Be Used Against Me In Court?
When a person chooses to remain silent after receiving his Miranda warnings, that
silence cannot be used against him in court. However, if a person has not
received his Miranda warnings, and remains silent, it is possible for that
"pre-Miranda" silence to be used against him. For example, if a person is arrested
for murder, or is told that he is a suspect, a typical innocent person will express
disbelief and may even try to present an alibi. It would be unusual for a person to
simply remain silent, after being informed that he is being wrongfully charged with
murder - even people who know their right to remain silent will often express
surprise. A prosecutor may subsequently argue that the "pre-Miranda" silence
resulted from the fact that the defendant was not surprised that the police
"figured it out."

How Do I Protect Myself From Having My "Pre-Miranda" Silence Used
Against Me?
If you are under investigation for a criminal offense, you can prevent
"pre-Miranda" silence from becoming an issue by stating, "My attorney told me
never to talk to the police without talking to him first. Do I have to answer your
questions?" Once informed that you have the right to remain silent, no negative
inference can be drawn from your exercise of that right. There is nothing wrong
with making your attorney responsible for your choice to remain silent -- it looks a
lot more suspicious if you simply refuse to answer questions than if you present
the explanation that your attorney gave you standing advice not to answer
questions.

If I Remain Silent Or Ask For A Lawyer, Won't The Police Think I Am
Guilty?
The police tend to draw a negative inference from the fact that suspects refuse to
answer questions, or where suspects hire attorneys ("lawyer up") before they are
charged with crimes. However, there are many cases where the only evidence
against a defendant is his confession, or where an innocent person finds that the
police have misinterpreted his statements. In one notable case, a police officer
was a criminal suspect -- he made a taped statement, expressing his innocence.
Subsequently, he was shocked to hear his tape recorded "confession" used
against him in court. As it turned out, his statement was recorded on a used tape,
which contained a confession from a different case. Part of the old recording,
immediately after the end of the police officer's statement, was presented as the
defendant's "confession." If that can happen to a police officer, obviously it can
happen to you.

If I Choose To Remain Silent, Or Request An Attorney, But Later
Decided To Answer Questions, Can They Use My Statement?
If the police do try to question you after your arrest, they are supposed to cease
interrogation if you exercise your right to remain silent or request an attorney. It
should be noted that the request for an attorney is "more powerful" than a
request to remain silent. Courts tend to view police claims that a suspect changed
his mind about having an attorney with much more suspicion than claims that
the suspect changed his mind about remaining silent.

The police use numerous techniques to get suspects to change their minds about
remaining silent. One very simple technique is to use silence against the suspect --
the officer explains, "You don't have to make a statement, but I still have to write
up this report, describing what everybody says that you did." The officer, in front
of the suspect, then starts to type out his report, saying nothing to the suspect.
It is common for the suspect to break the silence, and to choose to make a
statement.
