That is to say:

“Better to be judged by twelve than carried by six.”

Or in other words:

When contemplating the personal use of deadly force with respect to self-defense from perceived imminent, immediate, and grievous bodily harm to oneself or to others, and questioning whether justifiable homicide would be ruled; it is important to consider that it is preferable to be alive and judged on that matter by a jury of twelve of ones peers than to be dead, in a casket, and carried by six pallbearers to ones waiting grave.

Unknown source on the quotation.
