At a feel-good, PR-style luncheon where many of the guests are whispering on their cell phones, Dallas City Councilman Gary Griffith is not only listening intently to the speaker but actually making tiny little notes with a ball point pen on a small leather-backed notepad that he keeps pulling out and then redepositing in his breast pocket. It's typical of the quiet, behind-the-scenes intensity and thoughtfulness this freshman member of the council brings to the mission. Often unheralded, Griffith has helped the council pluck its way through several political spiderwebs already, including supplemental pay for injured cops, hiring a new police chief and countless neighborhood battles over streets and parks. So far he's been modest, cautious, smart and effective. Of course, he hasn't been sipping the Marilla Kool-Aid all that long. Let's try to get some more good out of him before they bring the refills.
