The the short answer is no. Here's why.
The police will even try to be your friend and give you whatever you want to eat or drink in order for you to cooperate with them. It's because if you cooperate it makes their job 100% easier. They know that. You should know that too. Keep remembering this is State v. You and not State and You. They also know that if you ask for an attorney that they have to stop questioning you, so until you say the magic words, "I want to speak to an attorney" don't think they are done with you.
In the end, you may decide that you want to cooperate, but that decision should only be made after a consultation with an attorney. Don't let the officer convince you that he'll put a good word in for you with the district attorney or the judge. The only time I ever see a police officer in court saying something is when he is on the stand testifying against the defendant.
