ABOUT THE METROPOLITAN POLICE SERVICE (MPS): London's Metropolitan Police Service (MPS) is one of the largest police forces in the world with over 45,000 staff, 31,000 of whom are police officers. These officers work across 620 square miles, protecting 7.2 million people across London. The MPS is the world's largest user of Axon Body- Worn video (BWV) technology today, utilizing 22,000+ Axon cameras. The MPS is one of only two UK Forces accredited by the Surveillance Camera Commissioner and was the 1st UK force to digitally share evidence with the Crown Prosecution Service (CPS). OVERVIEW: The MPS manages and digitally shares its BWV evidence using Axon's platform by integrating into the MPS's digital case file system called COPA (Case Overview and Preparation Application). All MPS BWV footage (approximately 240TB of data) is securely stored on the Microsoft Azure Cloud. Officers can now truncate clips, make simple redactions and tag evidence with a few simple clicks enabling the CPS to make quick and informed decisions. Officers are able to set the access permissions for who can view and download the digital evidence, enabling the CPS to onward share with the defence and enable playback in court using click-share on a variety of devices. Now, thanks to, the process of sharing BWV evidence with the CPS is seamless, secure and is speeding up Criminal Justice for all. Justina Brown from the MPS's BWV team said, "integrating in our digital case files provides us with the safest and most secure system we have seen to date, and we are successfully sharing over 5,500+ clips a month using this method". BUSINESS CHALLENGES: Previously, officers would have had to burn evidence to discs before delivering them to the CPS via courier, which was cost and resource intensive, posing many challenges including poor security, the risk of losing data and the lack of effective audit trails. Officers had to burn a minimum of three DVDs for each separate piece of evidence, meaning if the incident was captured by a CCTV camera, a dashboard camera or a body camera, the officer had a total of at least nine DVDs. The majority of agencies today are still using this method of sharing. SOLUTION: Axon, in partnership with Microsoft, has enabled the MPS to share BWV with the CPS securely by supplying a software-as-a-service (SaaS) solution within the Cloud. The shift away from cumbersome legacy systems in turn has provided the MPS with substantial cost/resource savings.
