I'm not sure if that's the case. The article seems to be saying that they did actually find the drugs in the alley, and the officer was essentially recreating the finding of the drugs using his body camera. Obviously that isn't an acceptable way of using the body camera, and it has the unfortunate effect of causing the case of a potentially guilty drug-dealer to be dropped.
Presumably because he didn't know they were going to find anything. We already know he didn't know about the 30 second thing. If he did, it wouldn't have been a problem, he wouldn't have needed to do the recreation at all.
I'm saying it was possibly illegal but not amoral. There is a difference. Compare to planting drugs to frame someone innocent.
