That has affected the courts. David Walsh-Little, chief attorney in the felony trial division of the Office of the Public Defender in Baltimore, said the percentage of his attorneys' cases that are drug-related dropped by 10 percent in January, compared to January 2015. In 2011, drug cases represented about 35 percent of all felony cases in the division, he said. So far in 2016, that number is closer to 23 percent, he said.
