The version control system you describe was originally designed for text-based code, and would probably impose significant time costs on the officers, and delays on the suspects. Police cameras, which could be required to be turned on at any stop, or before any search/arrest would provide the same information (if the officers were required to state their cause aloud). The cameras could even be set to save 5, 10, or 15 minutes of footage before 'activated', so that the police would not be able to claim they 'were in a rush'. This system could also be automatically activated by a gunshot or other sound.
