Actually, there is one more thing you should say. “I think I may be having a heart attack.” This makes the police summon a medic, who will evaluate you, and give you time to have your heartbeat slow back down to close to normal.
My attorney gave me a copy of his business card; the front of it is conventional, with his name, office number, e-mail address, etc. His home phone and cell number have been added. Officer:
If I have given you this card, it is because in fear for my life it has been necessary to take actions to defend myself. I am willing to sign a criminal complaint against the attacker. I will also point out witnesses and evidence. This is a stressful and traumatic experience for me. Therefore I wish to make no further statements until I have spoken with my attorney. Also, on his advice, I do not consent to any searches. I will cooperate fully once I have consulted with my attorney and he is present. As a lawfully armed citizen, I ask you for the same courtesy that you would show a fellow officer who was involved in a similiar situation.
Thank you for your understanding.
In the event that card doesn't work, there's a second one available. It's on the back of the personal card of the United States Attorney for this district, and reminds state and local law enforcement officials that any deprivation of any civil right of a U.S. citizen is a federal felony, and also constitutes a state felony of Official Misconduct that can cost them their job, even without a conviction.
Better to have and not need than to need and not have.
Splashing a little water on the front of your pants and pointing it out to the police also helps bolster your claim that you were in fear of your life.
