If you are taken to a police station and the police begin to question you, remember "Silence is Golden."  You should immediately tell the police that you want an attorney.  You must make it very clear that you want to speak to an attorney.  The best phrase to use is "I want an attorney present during this interview."  Once you have requested that an attorney be present, the police must stop questioning you.  However, you must be careful not to initiate any further conversation with the police until an attorney arrives, since this could allow the police to begin questioning you again and your statements after that time could be used against you. 

People who are being interrogated are often told that if they will just tell the truth, things will go easier on them.  This is almost always a false statement.  Don't fall for it, since the police can lie to you to get you to make an incriminating statement and your statements can still be admissible.  In most cases, as long as the police don't beat you up, deprive you of food and bathroom facilities, your statements will be considered voluntary and admissible against you in court.
