Chesa Boudin, the leftish district attorney for San Francisco, claims to have reduced the jail population by nearly 40 percent since the onslaught of the epidemic. “That has created the conditions for the jail medical team to implement some level of social distancing, to isolate people who show symptoms, and to find ways to meet the medical needs of folks who have other medical conditions besides Covid-19,” said Boudin, whose 75 year-old father, David Gilbert, is serving time for the 1981 Brinks armored car robbery in New York.
