Humorously speaking, I'd like to think being a brother forum member with the great Mas Ayoob would be a great thing to have in your arsenal. Should any of us be involved in a righteous shoot, I pretend that he'd be willing to at least provide some documents that help in our justification...
He does great things for 'us kind of folk' regarding your very question. Like Glenn mentioned, I'd suggest looking into some stuff Mr. Ayoob has written or cases he has worked.
