Courtesy of the Border Patrol’s official union, the National Border Patrol Council:
If you click on the link in the tweet, you’ll see that the actual headline reads, “Parents of dead Mexican teenager sue U.S. government“.
The tweet is in reference to the fatal 2010 shooting of 15-year-old Hernandez Güereca, who was on the Mexican side of the border throwing rocks at Border Patrol agents. An unnamed agent shot and killed Hernandez Güereca from the U.S. side of the border.
Video footage of the shooting exists. I fail to see how shooting a kid for throwing rocks from that distance is justified.
