If you were actually arrested for domestic assault, you should have been read your rights before the Miranda decision before further questions were directed to you and before you presumably made some incriminating statements about the situation you were arrested for.The police officer can ask you questions after you were arrested without telling you he was wired with a tape recorder. Possibly the taping of your statements post arrest without being read your Miranda rights could have been in violation of your 5th Amendment right against self incrimination. I suggest that you consult with a criminal defense attorney about your situation.
