And if the cops kill you anyway, they'll likely walk away scot free.
I say in all seriousness that that is already too much. Wait for your lawyer to tell you that it's ok to say that you shot a guy.
I recall a thread here on FR earlier this year where an employee in a gun shop (Houston?) shot an armed robber dead. He called 911 and said something like he had discharged his weapon within the Houston city limits, not that he had shot somebody.
