But it would help if documents pertaining to his case were disclosed promptly and not written after the events they purported to describe.
There is no requirement for police to write a memo detailing in minute detail everything they can think of when they get back to a station. Police only write up statements when a statement is needed and only with respect to the issue needed. Prosecutors don't want to have to read through 50 pages of crap to find one issue they needed to know about.
