I can think of a few reasons why you’d want to do that approaching a meth lab or a grow house.
Had they taken the computers and recording equipment in the raid, after finding they had screwed up, THAT would have been clearly anti-4th A.
I can't. They had already started their frontal assault. The people in the house knew they were there.
It's simple malicious destruction of private property that can record the mis-deeds of the police.

It would be much quieter to simply always carry a small spray can of black paint to spray over the camera. Obviously these LEO are not properly prepared.
