that gave closure to sharon frazier's family. you will hear a lot throughout the campaign about our dna labs, the state it is in, which is a failing state, and our dap's inability to address it either as police chief or as d.a.. i wanted to give you this issue because in the 21st century, dna is a critical tool, essentially -- essential to our ability to put the most dangerous and violent criminals behind bars and give closer to their families. every time we put a serial criminal, rapist, and murder behind bars, we are that much safer. as a dna expert, prosecutor for 22 years, and the leader of an elite trial unit, experience matters. i will bring my experience to my job and leave san francisco to a safer and protected city. >> thank you for inviting us and making this possible. i am the oldest one up here, but the newest member of the candidates for district attorney. i entered the race less than a month ago. the reason i entered was i was a district attorney for 20 years, but i have been a defense attorney for the last 16 years
