Do not speak with the police.
I can not emphasize this enough. You must think of each word that you say to the police as a new piece of evidence that will be used against you - not for you. Provide the police with your correct name and contact information and nothing more.
Our prisons are filled with people who talked to the police to tell "their side of the story."
This is a mistake!
When the police want to talk to you, they are looking for evidence of a crime and you are a suspect. If they had enough evidence to charge you with a crime, they would already have done so. To get more evidence, the police will manipulate you. A common tactic is to try to make you think that they are your friends and want to help "make it easier on you." The police are not your friends.
Remember, you have an absolute constitutional right to remain silent. You do not impair your rights by refusing to talk.
Write out the Events on a piece of paper.
Write out the chronology of events that occur during your arrest and/or detention. Did the officer stop you? What was his/her stated reason? What questions were asked? What procedures did the officer follow? Were you read your rights? Did they make a sound or video record the arrest?
When you are stopped by the police, it can be a very traumatizing event. this may make it very difficult to recall the procedures that the police officer followed. By making a written record of the events shortly after the stop or arrest, you may be better able to recall the events accurately when speaking with your lawyer.
Do not write down any events related to the crime that you are suspected of committing. Any such record could be used against you a trial if recovered by proper police procedure.
Contacting a Lawyer can only Help.
Many good defense attorneys offer FREE initial consultations. For that reason alone it is important to contact a lawyer before appearing in Court or speaking to law enforcement. It is a "no lose" proposition that cost you nothing except your time.
The lawyer will listen to "your side of the story" and is likely to provide you with information regarding the criminal court process, your worst case scenario and what you should expect.
Listen carefully to what the lawyer is saying. In most cases, your interests are best represented by having a competent legal professional in your corner.
After you retain a lawyer you can expect that the police officer's side of the case will be investigated. Holes may often be poked in the police reports generated by officers. In discussing your matter with a lawyer, always tell the truth. Your lawyer is there to represent you and to require the prosecutor to prove their case against you.
