If you are arrested, you have the right to obtain counsel. In the event that you do not have a lawyer, the police are obliged to provide you with access to a free lawyer. These lawyers, although paid for by the state, do not represent the police, government, or victim(s) of the crime. Their legal advice is not recorded, and their assistance is confidential.
A lawyer will advise you on your legal obligations with the police. Typically, someone in custody will need to provide their name, address, and date of birth. You are not required to assist in the criminal investigation; however, you also cannot willfully obstruct their pursuit.
You have the right to remain silent. If you have been advised of, and obtained, your right to counsel, whatever you say to a person in authority may be admissible in court and could be admitted in evidence in a trial and used against you.
If you are being investigated by the police, you should retain counsel and obtain legal advice; do not speak to the police before receiving advice from a lawyer.
