Let's simply take what Netflix recommends: 3 megabit / second for HD video, that means 32GB for 24 hours. Not too bad given you can get a 32GB microSD for below $10.
Netflix gets to squeeze and optimize in advance, once, for hopefully many hundreds of thousands of streamings.
Police body cameras are going to be a lot more like the dash came I recently installed for a trip. 1080p at 30FPS and slightly blurry gets me about 5 hours to a 32 'billion byte' uSDHC card.
That isn't so bad, you can fit a normal shift in to a 64 GByte space, and if you double that up again you'd get almost a whole day's worth of time.
The battery is an issue for sure, but then again Police already come equipped with a belt that has a lot of other stuff, and are usually deployed with a moving vehicle OR are stationed in an area where they will have a regular chance to return to a break room (which is where a natural battery swap would occur).
