I want to know the answer to the following question:
What can only Superintendent-ranked UK officers do?
All the background I'm provided with is that "However, certain higher ranks have additional powers to authorize certain aspects of police operations, such as a power to authorize a search of a suspect's house (section 18 PACE in England and Wales) by an officer of the rank of Inspector, or the power to authorize a suspect's detention beyond 24 hours by a Superintendent.". Is that enough to answer the question?
Answer: yes
