In late September, Bridgeport, Conn., criminal defense attorney Wayne R. Keeney was back in a comfortable place — the courtroom. “One thing I can say about this job,” Keeney told the Connecticut Law Tribune last week, “I’ve always liked it.”

But his appearance in Stamford Superior Court was not related to any particular case. Keeney was participating in a swearing-in ceremony to reactivate his status as a practicing member of the state bar. The criminal defense work that he loves, along with everything else in his life, nearly slipped out of his grasp as he battled a serious case of hepatitis C for 18 months, which led to near failure of his liver.
