It doesn't matter if the content is actually fair use since the content will just be taken down anyways with little opportunity for appeal because it's YouTube.

A bigger hurdle for the police department is the 1st amendment suits a systemized program would attract.

You would need to counternotice with your personal details. (And the cops abusing the copyright system would get a copy)

YouTube's Content ID ignores Fair Use.

Fair Use is an affirmative defence against copyright infringeement. That is, its effective power is used in a court of law as an argument in defence against a criminal or civil copyright complaint.

TL;DR: Present policy says "F-U" to Fair Use.

Hm. Gotta have faith in the algorithm. If that fails then maybe add to the list to make a phone call so you can go after them criminally for wiretapping.
