Was it mandatory to comply with such a request? I was under the impression that mandatory court orders need to be signed by a judge (not a prosecutor).
I do believe this request was pushing the legal boundaries as the law describes the request should be as specific and narrow as possible [0]. (with "as possible" being a rather big loophole)
