Immigrants and civil rights activists are questioning the Border Patrol and the Transportation and Security Administration officials' arrest and removal of three undocumented teenagers in San Diego.
Border Patrol officials say they were supporting a Transportation Security Administration operation when Border Patrol agents detained 21 people at the Old Town Trolley Station.
Agents say they sent all but two who had criminal charges back to Mexico.
Among the group were three minors headed to high school.
Questions swirl around the incident including what prompted the arrests and if the Border Patrol had consent to return the minors to Mexico.
Kevin Keenan directs the ACLU in San Diego. He says facts are still coming to light. However,
"It makes you wonder if this is the change President Obama promised us."
Border Patrol officials say they followed protocol.
TSA officials say they don't conduct racial profiling. They say their partners follow their own mission.
