Only if you knew by virtue of something like access to secret information (the things you'd have a security clearance to access).
If you see the police are gathered around your local 7-Eleven, you're absolutely free to post it.
If you know in advance that the police are going to be performing a raid on a meth house and you got that information by virtue of a security clearance (I assume they do have something of this sort like federal employees have, though I'm not sure the precise mechanisms) then you'd be violating the policies around that access. This could be illegal (just like a fed leaking secret or top secret information).
If you know in advance because the police have loose lips, but you are not personally under any kind of confidentiality policy, you're free to post it. So the loose lipped cops at the bars I used to frequent could have caused real problems for themselves.
