How much data can a police department generate?
Before delving into the more nuanced discussions of data storage, it’s vital to first understand exactly how much data the average police station can create. Each department will obviously have its own special needs, but a good place to start is the analysis of the Chula Vista, California, police department’s data storage given by Lieutenant Vern Sallee in Police Chief Magazine. Sallee stated that his station had 200 sworn police officers that were using body cameras in their daily rounds. After playing around with their current setup, Sallee’s department found that a 30-minute video demands around 800 MB of storage. Accounting for all officers with cameras, Chula Vista could generate around 33 TB of data annually. To put this in perspective, Sallee stated that this is roughly the same size as 17 million photographs. Again, it’s important to remember that this is a rough estimate for a single town. Chula Vista has just over 265,000 citizens, making it larger than the average American city. That said, such a population pales in comparison to the 8.5 million people living in New York City, and implementing a police body camera initiative in this kind of metropolis would be a whole different ball game. What’s more, these larger cities are the ones that need body cameras the most, as they generally have more violent crime requiring forceful police intervention. Clearly, simply finding a place to put all this data is going to be a challenge.
Keeping large portions of data for long stretches of time can be difficult.Privacy and security are huge concerns
Another major concern with these body cameras is the privacy of the people involved in the recordings. As stated, departments can’t delete a video until they are absolutely sure that nothing on it could possibly be useful in the future. This means that the actions of a lot of innocent people are going to be recorded and stored, and this has certain civil rights groups worried. In fact, a coalition of the National Association for the Advancement of Colored People and the American Civil Liberties Union presented some guidelines to legislators in 2015 attempting to govern how these recordings are treated. The group wanted to prevent an overreaching use of facial recognition software, as well as ensure officers were only allowed to watch their videos from the day after filing a report, according to CNN.“Police officers have the right to discuss personal matters without being listened to.”
