Part of the problem is this:
Q. How long are the videos kept?
A: Current policy is to indefinitely keep video recordings dealing with crimes. The Seattle Police Department is working with Department of Justice monitor Merrick Bobb to finalize policies for the body-worn cameras.
Are they deleting videos that DON'T deal with crimes after a set period? And why in God's name are they kept indefinitely? Anything the DA doesn't elect to prosecute should be deleted fairly quickly. Anything that hints at police misconduct or a criminal charge against an office is kept for the duration of the State Statute of Limitations.
