The notes also enable a person to understand exactly how they were caught, or other things that they may not have considered or noticed. It may cause the defendant to plead guilty, or may help their defence. Example: Defendant is driving on a sidestreet. Defendant sees police car behind him. Upon spotting police car, defendant takes careful note to drive posted speed limit and come to a full stop at all STOP signs. Upon crossing one intersection, defendant is stopped and ticketed for running STOP sign. Ticket says location is S/B DUPLEX AVENUE, for example. Defendant is furious and gets disclosure, thinking he was ticketed for not stopping after he spotted cop; in reality, notes show that defendant actually ran a stop sign four blocks prior, officer noticed from a distance, and officer only caught up to him at the intersection he THOUGHT he was ticketed for running the stop sign at. Defendant goes
and seeks to plea-bargain.
Conversely, could also show that wrong vehicle was stopped, officer lost sight of it, etc. Even if notes are not clear, Bookm said it best: If an officer plans to use his notes, defence has the right to see what information is in the notes.
