You Have the Right to Remain Silent and You Should Exercise That Right To Limit the Information That Can Be Used to Charge and Convict You
It's very simple - you should never speak to law enforcement without an attorney advising you. Whether you are yet to be charged and the police are just investigating or you have already been charged and law enforcement is trying to get additional details or a confession, you are not required to answer any questions. You have the right to remain silent and to have an attorney present during all questioning.
Many people are in a state of panic when they discover they are part of a criminal investigation and their first instinct is to speak to the police to "set the record straight." Even if you are innocent, this can be a huge mistake. The role of law enforcement is to arrest and charge and the role of the district attorney is to prosecute. Neither of those parties are working for you, so you need a criminal lawyer that is there on your behalf. Innocent people are charged and worse, convicted every day. Declining to speak to law enforcement without an attorney present increases the chances that this will not happen to you.
If you may be culpable in some way for a crime, then it is even more important to seek representation from a Raleigh criminal lawyer. Even if you may have done something wrong, the state has the burden to prove your guilt beyond a reasonable doubt. Having an attorney early on will limit the information that law enforcement is able to get their hands on to successfully prosecute you.
