We attach a copy of the summary of your interview at the police station. Read it carefully.
Interviews are often lengthy, and the summary provides edited highlights only.
The summaries are short and to the point - to the policeman's point, that is. The purpose of his summary is to demonstrate your guilt. Police officers may not include things you said, which you think are either very relevant, or helpful to you. The summaries are usually, but not quite always, accurate, so far as they go. Did you use the words.
