William Sessions, for­mer head of the Federal Bureau of Investigation, recent­ly point­ed to cas­es of defen­dants who were exe­cut­ed based in part on faulty hair and fiber analy­sis in call­ing for changes in the use of foren­sic evi­dence. In an op-ed in the Washington Times, Sessions told the sto­ry of Benjamin Boyle, who was exe­cut­ed in Texas in 1997. His con­vic­tion was based on test­ing con­duct­ed by an FBI crime lab that an offi­cial review lat­er deter­mined to be unre­li­able and sci­en­tif­i­cal­ly unsup­port­able.” Neither state offi­cials nor Boyle’s attor­neys were noti­fied of the task force’s find­ings before his exe­cu­tion. In two oth­er cas­es, inmates were also exe­cut­ed despite find­ings that their cas­es were taint­ed by unre­li­able foren­sic tes­ti­mo­ny from the FBI. Sessions said, I have no idea whether Boyle was inno­cent, but clear­ly, he was exe­cut­ed despite great doubts about his con­vic­tion. Such uncer­tain­ty is unac­cept­able, espe­cial­ly in a jus­tice sys­tem that still allows the death penalty.”

Sessions offered rec­om­men­da­tions for improve­ment at each step in the legal process: Courts must deter­mine if oth­er kinds of foren­sic evi­dence are trust­wor­thy and thus admis­si­ble. Defense coun­sel must rig­or­ous­ly review and chal­lenge any pros­e­cu­tion mis­use, mis­char­ac­ter­i­za­tion, or with­hold­ing of foren­sic evi­dence. After con­vic­tion, if new foren­sic evi­dence or tests become avail­able, pros­e­cu­tors and courts should not rely on pro­ce­dur­al tech­ni­cal­i­ties to pre­vent defen­dants from obtaining review.”
