I became a lawyer because my parents came from a country where there was no rule of law.  My great uncle was the longest held political prisoner in the world (sentenced to 30 years after a 30 minute trial).  Being able to practice law in a society that respects law and the rule of law and help those through that process has been one of the biggest blessings of my life.
