No, like all humans, they're self interested. They just want to be seen to do a good job protecting one of the states biggest earning and most well known companies in a high profile case.
I personally also pay more attention and go beyond the call for higher profile projects. That doesn't mean I'm involved in some kind of conspiracy.
It's one thing to suggest that the police will pay greater attention to high profile cases (with which I'd agree), and quite another thing to imply that the raid happened because Apple requested it.
Beyond that, could you point out the source of your assertion that Apple requested this? I missed it in the article, and that's the conspiracy you've raised.
If I were Apple, I'd ask the police to get the phone back from Jason Chen, hire my own people to get his address, and let the police do what they will, knowing that likely means a raid.
