"We do not have a policy that specifically requires deputies to ask for proof of citizenship," Kahler explained via email. "We do ask to see identification as a regular course of action during a motor vehicle or personal stop. Once they provide ID, we query the info through multiple databases. Should one of those databases provide an alert regarding the status of the individual, and indicate they have been flagged by immigration or federal authorities, we then contact that agency. That agency then provides direction on how to further handle the individual and whether or not to detain for further investigation."
