The question isn’t whether it’s a good thing, or even just fine, that ICE and CBP agents round up random people who appear to be foreigners with neither visible names nor shield numbers such that you can identify who engaged in illegal conduct. Stephen Miller thinks that’s swell, even if Gavin Newsom and others do not. The question is whether the State of California can make it a crime for federal agents to do so within its borders. The Ninth Circuit, unsurprisingly, in an opinion by Judge Mark Bennett, held it cannot.
Section 10 generally mandates the visible display of identification by law enforcement officers operating within the State. See Cal. Penal Code § 13654. It provides that any “law enforcement officer operating in California that is not uniformed . . . shall visibly display identification that includes their agency and either a name or badge number or both name and badge number when performing their enforcement duties.” Id. § 13654(a). “Law enforcement officer” is defined to include “any federal law enforcement officer.” Id. § 13654(d)(2). And “‘[e]nforcement duties’ means active and planned operations involving the arrest or detention of an individual, or deployment for crowd control purposes.” Id. § 13654(d)(1). An officer’s “willful and knowing violation of [§ 10] is punishable as a misdemeanor” under California law. Id. § 13654(c).
