The simple answer is probably not. Most people believe that a case may
be thrown out of court if the police officer does not provide them with
their "Miranda warnings" when they are arrested. I am confident
that this belief comes from the abundance of television programs that
show the Miranda warnings given whenever someone is being arrested.
A Miranda warning is necessary if the police officer interrogates someone
and wants to use their responses as evidence. If the police officer fails
to give you a Miranda warning, nothing you say in response to the questioning
can be used as evidence to convict you. Additionally, under the "fruit
of the poisonous tree" rule, if the police officer finds evidence
as a result of an interrogation that violates the Miranda rule, that evidence
is also inadmissible at trial. For example, if you tell the police officer
where a weapon is hidden and it turns out that you gave this information
in response to improper questioning, the police officer will not be able
to use the weapon as evidence unless the officer can prove that they would
have found the weapon without your statements.
