Under the microscope: Maryland high court considers limiting ballistics evidence used to link guns to shootings

A television in Baltimore Circuit Court showed a magnified picture of spent cartridge casings taken through the lens of a microscope. If a juror didn’t look closely, they might confuse two rounds for one. Half the image showed a casing found on a sidewalk in Southwest Baltimore, where a man and woman were killed early on a frigid morning in November 2019; the other half showed a casing test-fired from a handgun confiscated later that day from one of the defendants.
