Question, wouldn't the legality of such wire taps be a problem in court? I'm pretty sure one can't use this in a trial without providing information as to how they acquired the data. Without a warrant, even the most damning of evidence would get thrown out:
Since they've already admitted to not putting this type of surveillance in police reports all they have to do is "independently" get another source of information.
"So officer, how did you come to find the evidence in a completely unrelated location far from where you typically work?"
"Well, I was out for the day and I tripped over it. Amazing right!"
