Do you need to use photo id to check into prison for visitation?
Yes but it's not like there are flashing lights and sirens at the police station every time someone in prison gets a visitor. Nobody at the station knows Dexter is visiting because nobody feels any need to go look at the logs to see who's been going to visit Sirko.
And while Sirko is under surveillance there's no way the uniform cops would know who he was talking to at lunch.
