Five years almost to the day before President Donald Trump’s border officers blocked migrants with tear gas, authorities under President Barack Obama used identical tactics along the same stretch of border near the San Ysidro Port of Entry, according to 2013 press accounts.
The San Diego Union-Tribune reported November 25, 2013:
The incident occurred about a quarter-mile west of the San Ysidro border crossing in the Tijuana River channel. No one was seriously injured, no shots were fired and no arrests were made, said Mary Beth Caston, a Border Patrol spokeswoman.
The group first approached a lone agent stationed about 1/8 of a mile north of the border. They ignored his commands to stop, so he fired pepper balls to try to stop them and protect himself, Caston said.
