What’s different about the detention of Jennifer’s brother is that it took place on the grounds of a state courthouse. By waiting outside the courthouse, immigration agents appear to be complying with California law, though it’s unclear whether the word “courthouse” in the law includes the grounds outside the courthouse. In Butte County, immigration enforcement agents conducted an operation inside the county’s Oroville courthouse on July 28. Gavin Newsom signed Saturday meant to keep immigration enforcement agents out of schools and hospitals, it’s unclear what California law enforcement can actually do to enforce the law forbidding immigration agents from making arrests inside courthouses. The Obama administration in 2011 designated schools, hospitals and religious buildings as “sensitive locations” where immigration agents need permission to operate.
