Supreme Court justices appeared divided on whether to let foreigners bring civil rights lawsuits in U.S. courts as they considered a bid by a slain Mexican teenager's family to revive a lawsuit against the Border Patrol agent who shot him, with Justice
Brett Kavanaugh emerging as a potential pivotal vote.
The court heard arguments in the family's appeal of a lower court's ruling dismissing their case against the agent, Jesus Mesa, who had fired across a concrete spillway into
Mexico from the
Texas side of the border during the 2010 incident, striking 15-year-old Sergio Adrian Hernandez Guereca in the face.
