Never speak to the police without legal counsel. PERIOD.
The Supreme Court of the United States (SCOTUS) ruled on June 1sr. 2010 that saying anything after you are mirandized waives your right to remain silent. (Berghuis v Tompkins)
Invoke your right to remain silent and to seek counsel immediately, whether arrested or not, then keep you mouth closed. Provide I'd if asked and nothing more.
