I have a friend that is a criminal defense attorney.His advice was to tell the police that due to the stressful nature of the circumstances,you'd rather not make any comment until you confer with an attorney.He said most,(not all), officers will understand and respect your decision and stop asking you questions...
The responsing officers had BETTER stop asking questions!
Make no mistake: LEO's responsing to a call about a shooting will enter, see dead guy on the floor, and see you there.
If I am responding, the FIRST thing out of my mouth will be this:
"Sir (or ma'am), let me make this very clear: at this time you are NOT under arrest; however, you are not free to leave yet. Therefore, I must advise you that you have the right to remain silent..."
The "Miranda" warning is triggered whenever the person being questioned:
a. Is no longer free to leave (investigative detention, or "Terry Stop")
b. Is the focus of any criminal investigation, or
c. FEELS that they are no longer free to leave.
Ask yourself: Do you think you would be free to leave immediately if the police are responding to a shooting? More than likely, no.
Thus, "Miranda" is triggered. You will be advised of your rights.
So, what to do? Other posters have said it already:
1. Make SURE you do not meet the police with a gun in your hand.
2. Do NOT, under ANY circumstances, disturb the scene.
3. Lawyer up! (The mental image of a herd of attorneys on horseback galloping in comes to mind.) If you tell me you want an attorney, I won't even talk to you until your attorney gets there.
(Actually, when I first arrive, my questions more than likely be, "Are you OK? Is your family OK? Are you hurt in any way? Might want to sit down and relax, this could take a while." At least, that's the way I'd do it...can't speak for any other officers but myself, of course.)
