The testimony given by most of the witnesses was corroborated by secretly taped and recorded telephone conversations without which defense attorneys would have disputed the accusations and charges brought against the target.
The affidavit did not state the specific methods of tapping the telephones but the following can be assumed:
That several recording devices were used, whether digital or analogue. The devices were power efficient, able to record over extended periods at a time, small and conceivable, exceptional audio quality as well as date and time stamped as was shown in the evidence. Despite the dangers involved or compromise to the investigation some of the telephone systems could have been tapped by hard wiring or the use of transmitters. This meant gaining access to the target location. The best place for this activity would have been the target’s affiliate office (Friends of ROD BLAGOJEVICH). The reason being that of the three locations, that will have the least amount of security compared to the target’s residence and official office. (Jenkins, 2010 p.274 -
