border patrol says it doesn t use race as a factor for stops, but won t say what it does look for /

The chief of San Diego's Border Patrol section said he can't disclose what agents glimpse for before stopping someone,but that race and ethnicity don't come into play. A review of enforcement actions recorded between 2011 and 2014, though, and shows agents stopped people for sometimes ambiguous reasons like sitting up straight or driving slowly.
