Key legal question
Whether the suspicion required for security detention could rely on the incidental finding from telephone surveillance and subsequent investigative measures.
Extracted holding
The detention judge could rely on the evidence for the purpose of assessing suspicion; admissibility of the evidence is primarily for the trial court, and the later authorization and ensuing investigations were not shown to be unusable.
Extracted reasoning
Questions of evidentiary admissibility, especially for formally defective evidence, are mainly for the trial judge. In detention review, such evidence may be used to assess suspicion. The incidental finding had been subsequently authorized, and later confrontations and investigative steps were available for consideration.
