1. the footage shouldn't be public. there's a lot of interaction that cops deal with which is embarrassing and private for individuals. your underage arrest has to live with you forever? your suicide attempt or domestic issues should be open to prying eyes? no, no, no
2. the footage shouldn't be under the control of local police departments. "oops, sorry, i 'bumped the server' and we lost the footage of that controversial shooting by my buddy nate. oh well"
state level? federal level?
and then really solid rules about who gets to access what footage must be enacted. something similar to HIPAA rules and fines
