Entering the Age of Body-Worn Police Cameras (arstechnica.com)
An anonymous reader writes: Cyrus Farivar writes about what's being called a new era in policing: the era of body-worn cameras. They're gaining a foothold in departments around the U.S. after a year of increasing tensions between police and citizens, caused by a series of high-profile shootings. Several research groups are busily evaluating how the cameras affect the way police do their jobs. Many officers welcome the technology — in addition to providing evidence backing up the use of force, it often helps with investigations, capturing details they may miss at the time of an incident. Farivar even goes through a couple of simulated encounters, while pretending to be a cop. The camera easily shows him everything he did wrong. In this way, police officers can also review encounters for training purposes. As more departments adopt them, it's looking like a win-win — police benefit, and the public gets access to some much-desired accountability.
One of the effects of body cameras is complaints against the police go down:

Policing involves dealing with people who are motivated to lie; lie to the police and lie about the police. All cops hear all day long are lies lies lies and some of those lies get pointed at them. It's true that cops are less likely to abuse their position if they know they're being recorded but that also holds true for citizens lying about cops' conduct.
The net effect is complaints go down, but there are two forces giving rise to that effect; it's not just the police changing their conduct. Just sayin'
Storing years of video data is trivially easy if you know what you are doing and not wildly costly. Most of this is never going to be looked at, so HSM with say 1PB of active disk and as large a library as you care should (100PB would be trivial) do the trick. Replicate over a couple of sites. Push everything over say six months old to tape, expire anything over 10 years old unless flagged in advance. One could easily do that for 20million USD, excluding the cost of the data centres. We are talking say 2 racks for the disk storage and servers and however much space you wish to donate to the tape libraries.
I am not sure what the physical foot print of a fully tricked out IBM TS3500 tape library is but their web page tells me that max capacity is 2.25 Exabytes, mix in some TSM and GPFS (or Spectrum Scale as they call it now) and jobs a good one.
Large scale storage is only a problem for those that don't know what they are doing.
