Moore denied recording any of their conversation, but was arrested after police obtained a search warrant for the phone and found the file on the memory card.



Dressed in a brown leather jacket, white pants and black glasses, Moore testified in a soft but hurried tone that she was upset when the officers started talking about "other options."



"Is that when you decided to turn on your tape recorder?" asked Assistant State's Attorney Mary Jo Murtaugh.



"Yes," Moore replied, her voice squeaky with tears.



Moore denied prosecution claims that she was wavering on whether she wanted to file a formal complaint, which required signing a sworn affidavit.



"I was sure about what I wanted to do –I wanted him (the officer) to be at least fired from his job," Moore testified. "I wanted justice, I wanted to be protected."



Under Illinois' eavesdropping law, making an audio recording a law enforcement officer or court official without the consent of all parties is punishable by up to 15 years in prison. The law does provide an exception allowing citizens to obtain evidence through a recording device if they have a "reasonable suspicion" that a crime is about to be committed.



The case against Moore has caught the attention of civil libertarians who believe the law is unconstitutional. Earlier this month, a group called the Chicago Taskforce on Violence Against Girls and Young Women submitted a petition with more than 3,000 signatures demanding that Cook County State's Attorney Anita Alvarez drop the charges.



The ACLU also filed two recent lawsuits challenging the law, but both have been thrown out of federal court.
