It's a bit wordy, but it's not really asking for anything too special. Something like "I'm a police officer with ABC department, and I need to know which drugs Mr. XYZ has purchased between [x] and [y] in regards to a criminal drug trafficking investigation I am investigating" seems to satisfy all of the requirements. * "administrative request": the officer is asking * "the information sought is relevant and material to a legitimate law enforcement inquiry": they are real police, and they are investigating a crime regarding this person and these drugs. * "the request is specific and limited in scope to the extent reasonably practicable in light of the purpose for which the information is sought": It is about Mr XYZ, and it is about drugs he purchased, the crime being investigated is about the same. * "and de-identified information could not reasonably be used": because it is specifically about Mr XYZ
