I've been called to jury duty three times.
Every time I'm selected for a panel, I never get past the preliminary screening (called "voir dire"). As soon as the lawyers find out about my education, training, career, experiences, friends, associates, professional associations/organizations . . . and ~ as Mike said, 'IQ' ~ . . . I'm done. Every prosecutor wants me on the jury and no defense attorney wants me in the courthouse.
Their loss. I'm a whole lot fairer and impartial than they can ever imagine. They stand a better chance with me than with a lot of sidewalk civilians.
But, THEY (defense attorneys) profile!
