On the back of some recent news articles and interesting twitter debate, I thought I would link to Mathews Articles on BWC’s over at the AMPED Blog.
Sky News article on Security fears on BWC storage
Storage issues and concerns were highlighted in research by University of Cambridge

So, after all the research, all the trials, all the ministerial promises….. After all the technical solutions and all the privacy concerns…. what do we have at the end?
A bit of a mess to be honest!
It is clear that Law Enforcement is being pushed down a road that hasn’t been finished. (I’m using that road analogy again!) It isn’t really ready to handle the rapidly developing technology or adequately manage the huge amounts of digital Multimedia Evidence. It’s struggling to put something in place because its been told to do so, and then doesn’t have the finances to do it properly.
As Matthew states in his Conclusion, after looking at the impact on society, the whole thing is being done the wrong way round.
…and because of that, there will be mistakes during these early years. Evidence will be of poor quality, evidence will be lost or deleted accidentally. Video will be processed incorrectly and integrity issues will be raised. Just as the public ask questions as to why a piece of CCTV is so poor, those same questions will be asked of BWV.
Lets quickly look at one of the issues mentioned here.. Integrity.
Throughout the entire lifespan of a piece of recorded video, the original data itself cannot change. If it gets transcoded when it gets cut or trimmed, it has to be logged and recorded. If not,the integrity could be called into question. Why? Well, as Matthew again states in the Amped series, there will be a lot of video that requires analysing in order for it to be interpreted properly. The enhancement of certain aspects of the video will, in many cases, assist in this process. When unnecessary and potentially damaging transcoding takes place before it gets to an analyst, any work afterwards is either going to be made a lot harder or even worse, call into question the integrity of all that hard work. A scientific and structured process must be used in order to ensure transparency and evidential admissibility.
What’s needed then?
One word – PATIENCE.
By not rushing into things and conducting small but lengthy trials, Law Enforcement will be in a better position to evaluate all the issues before making important decisions.
Its therefore very important that those people in IT departments and project teams who are tasked with implementing these trials need to listen to those people who deal with video from an evidential point of view – the Forensic Video Analysts.
