The thing is --- this is all about Mexicans --- the victim was from Mexico --- he just attended school in the USA which is very very common. He was back in Mexico for whatever reason and got kidnapped and killed by the Mexican police and other drug cartel members. One was a double agent informant --- which is why certain arrests were made when some drug kingpins tried to cross the border.
What I get out of the article is that they're blaming the US because they thought the US agents should have called the game before he was murdered.
