Of course that was the point. But malicious broadcast of copyrighted material to trigger automated enforcement systems sounds pretty far from "fair use" to me. Say nothing of the bad publicity when some video is just so bad it hits the news and now your IP is the soundtrack to a cop beatdown.
When you look at it from a legal "use it or lose it" and corporate risk perspective it's quite surprising that Disney didn't even sent cease and desists.
Edit: Of course you don't lose the copyright but your ability to litigate someone else's unfair use is a lot weaker when their lawyer can trot out a million examples that you were fine with.
Copyright isn't "use it or lose it"
Disney seems to be taking a very hands-off approach when it comes to government use, so I doubt they'll do anything about this police case.
