The police did not read me my rights. Does that mean that the arrest is invalid and the charges will be dismissed?
The rights you are referring to are commonly called Miranda Rights. These rights are only applicable when law enforcement seeks to have a conversation with an accused about their behavior. In the event that law enforcement questions an accused, law enforcement must read them their rights. Those rights consist of the right to council and the right to remain silent. If a law enforcement officer reads you your Miranda Rights, invoke those rights and do not answer any questions.
