One small piece of metal can change a person’s life forever. On Saturday, the Teva Interns and Karabots Junior Fellows came together to address issues in forensics, ballistics, and gun violence. Together they met with Mark Williford, a forensic ballistics expert and formerly an officer in the Philadelphia Police Department. Williford shared his experience as a police officer and crime investigator, as well as accounts from growing up in Philadelphia and his firsthand encounters with violence. More than just addressing the science of ballistics, Williford challenged the students to critically examine the impact of gun violence on individuals and communities.
