Having worked with law enforcement I can expand on this - car dash cam footage takes an impressive amount of storage as well. Given how the cameras are triggered, sometimes the footage is not needed or useful and therefore can be deleted. In other instances, depending on case charges and footage, the video has to be kept until further notice - the word 'indefinitely' is rarely used but that is the implication. Of course the body cams adds to this.
