I think police body cameras are needed but I don&#x27;t understand the need to retain all of this data for months or years.  These body cams are probably going to pick up a lot of people whether they are involved or not with the police activities being recorded.  Storing all this data indefinitely is likely create huge privacy problems going forward.<p>I think the data should only be retained if it is relevant to a serious incident (say where someone was killed or seriously injured or felony charges are filed) or to a complaint that is filed in a timely manner.  I would think an appropriate storage time would be from 2 weeks to 1 month.  That should be enough time to assess whether an investigation is likely to be opened requiring the data and if complaints are filed outside of this window in cases not involving serious consequences, I don&#x27;t think I&#x27;d see a problem with those complaints being time barred.<p>I realize this can also be a problem with other surveillance cameras but many of those are under private control and so not directly accessible to government or to hackers, by being stored in one place.  Also, I may be wrong but I doubt most surveillance cameras are recording the video for long periods of time.
