San Francisco's Sanctuary Policy on Trial

People from all sides are demanding that San Francisco change its “sanctuary” policy for undocumented immigrants following the killing of Kathryn Steinle (SteinLee), allegedly by Juan Francisco López Sánchez... a Mexican felon deported five times. He has pleaded not guilty to first-degree murder.
The policy limits cooperation between local police and federal immigration agents. It allowedt López Sánchez to walk out of jail in March despite a request from Immigration and Customs Enforcement to hold him.
Hillary Clinton and California’s two Democratic senators, Barbara Boxer and Dianne Feinstein, have joined Donald Trump and other Republicans in condemnation of the policy.
