An officer of the former US-backed military regime of El Salvador will stand trial in Spain for murdering civilian dissidents.

It is noteworthy that the US knowingly sheltered this murderer for 15 years.

El Salvador's other elite repression unit was called the Atonal Battalion. They used to torture prisoners by making them listen to Schönberg's music for hours on end ;-{. (I wish that were true, but I suppose they did much worse things.)
