I don't think that's a fair characterization.

> When asked by a reporter if police had the suspect’s name, Adams said, “We don’t want to release that now. If you do, you’re basically giving a tip to the person we are fine with seeking, and we do not want to give him an upper hand at all. Let him continue to believe he can hide behind a mask.”

Grammatical flub aside ("the person we are fine with seeking"), he is just saying that he doesn't want to say anything about the info being requested. The police release information that they have decided is in their interest to release. Everything else is classified confidential by default.
