He is also a member of the State Bar of California.
In 1995, David spent nearly a year building the defense of a young man charged with molesting two young girls. Although the evidence seemed overwhelming at times, His investigation showed the charges rested on poor interviewing and false statements. A jury acquitted the man on all four counts. That trial showed him how easily an innocent person can be convicted.
