Recently, a woman in San Francisco was killed seemingly randomly allegedly by an illegal alien with a long rap sheet of violent crime, deported five times. But he had been under city detention fewer than three months previously – except that San Francisco, as part of the “sanctuary movement,” long ago began to refuse to forward information about illegal immigrants it detains to the federal government, even though legally local law enforcement agencies must do so. Following the law enables the Immigration and Customs Enforcement Agency to take custody of and deport them.
It’s no accident that “sanctuary cities,” or those like San Francisco with an official policy of law enforcement not asking about citizenship status, are larger cities with higher proportions of immigrants that have higher crime rates. Given that population studies of the nation’s jails show these contain disproportionately more non-citizens than their incidence in the general population, and that a sample of diverse local jurisdictions reveals the proportion of illegal aliens jailed is much higher than their estimated population proportion, it’s likely that sanctuary cities (which would not keep citizenship statistics) have even higher and more disproportionate numbers of illegal aliens imprisoned. While the valid data about this are uncoordinated, overall they point to increased numbers of illegal aliens elevate criminal activity.
