The expectation to privacy and the admissibility of the evidence is closely tied together. The problem here is that I would argue that a reasonable person would not expect that his or her conversation in &quot;hushed voices&quot; (from the article) would be recorded by the normal security cameras located in the public space.<p>Without knowing the details, it&#x27;s really hard to say, but it sounds like this was a very targeted operation more similar in nature to bugging the home than to a general purpose security camera catching a glimpse of someone on the street.
