During a police interrogation in Boston, you have several rights that are protected by the law. These rights are aimed at ensuring fairness, preventing coercion, and safeguarding your constitutional rights. Here are some important rights you have:

1. The right to remain silent: You have the right to remain silent and not answer any questions asked by the police. This is based on the Fifth Amendment of the United States Constitution, which protects you from self-incrimination. You can simply say, "I would like to exercise my right to remain silent."
2. The right to an attorney: If you are being interrogated, you have the right to have an attorney present. This is based on the Sixth Amendment, which guarantees the right to legal counsel. You can say, "I would like to have an attorney present before answering any questions."
3. The right to stop the interrogation: At any point during the interrogation, you have the right to stop answering questions and end the session. You can say, "I am choosing to end the interrogation now."
4. The right to know the nature of the interrogation: You have the right to know why you are being interrogated. The police should inform you of the nature of the investigation or the offense they suspect you of committing.
5. The right to be free from coercion or intimidation: The police are not allowed to use force, threats, or any form of coercion to obtain a confession or information from you. If you feel coerced or intimidated, you should clearly express your discomfort.

It's important to remember that these rights are not just applicable in Boston but are protected by the United States Constitution. If you believe your rights have been violated during a police interrogation, it is advisable to consult with an attorney who can provide you with specific legal advice.
