Don't Talk to the Police - Ever
First step: Read about the "five magic words", memorize them, and do not ever say anything but the five magic words in any encounter with the police.
Next: take the time to watch this video on how to properly handle a police encounter.
Finally: Practice the five magic words and what you learned from the video, via repetition, just as you do with dry-fire practice.
When bad things happen (and the odds are virtually zero that a police encounter with any of this blog's readers will be anything other than a bad thing), your practiced repetitions will help control the damage.

Silence is golden, amigos....
