This whole situation has been blown out of proportion by the Brazilian authorities who are desperate to redirect all of the bad press they have received over the Olympics fiasco.
They see the U.S. swim as their salvation. They will continue to paint them as “Ugly Americans” until the bad press for Rio stops.
I think they've created worse press by inadvertently portraying themselves as having coerced confessions to save face.
They look more like a Banana Republic than they would had they just simply said "In a city of 6 million, sometimes you get a robbery."
Inviting scrutiny of their claims has backfired on them in my perspective.
