Unless they confirm with the police that they are able to release the information; we won't know at the time whether or not it can cause harm, but we will know when they call.
So provided they contact us, we don't have an issue. It is when people feel they can find a loophole by interpreting it to mean, “I know I can't release it if they ask me, but I can choose to release it on my own; therefore, I am covered.”
