A criminal investigation by a state or federal law enforcement agency will be an experience unlike any other you will ever face. The ultimate goal of such an investigation is not merely an injunction or money settlement, the goal is you!
The first instinct of people who are being accused is to defend themselves by explaining the innocence of their conduct to the police. This may not always be the best approach as the state will seek to introduce any damaging statement you make. You may think that you are doing yourself a favor, but in reality you are probably not. You have the right to remain silent. It is a very valuable right and one you should exercise. Remember, the police are allowed to lie to you. It is considered a good investigative tool. Don't let them trick you. Always ask if you are free to leave. If they say yes, then politely excuse yourself and go. After you leave, it is wise to call a lawyer to discuss your situation.
