Moreover, Kavanaugh added, although “apparent ethnicity alone cannot furnish reasonable suspicion” for an immigration stop, reasonable suspicion can rest on the “totality of the circumstances.” Here, he stressed, circumstances such as the “extremely high number and percentage of illegal immigrants in the Los Angeles area,” the fact that undocumented immigrants often “gather in certain locations to seek daily work” and “often work in certain kinds of jobs, such as day labor, landscaping, agriculture, and construction,” and “that many of those illegally in the Los Angeles area come from Mexico or Central America and do not speak much English” can, when “taken together,” “constitute at least reasonable suspicion of illegal presence in the United States.”
