That's exactly the case I was thinking about with my comment

1) Police don't care that APPLE doesn't want to reveal its methods, and 2) Unlike the Stingray, it wouldn't be illegal for them to use iMessage evidence in court if Apple provided it to them (especially with the use of a warrant!)

I think it's more about the police not wanting the public to know that iMessage is owned; having trusted-but-broken communication services is a serious advantage for them.
