Invalid Litter Dept.

is a song by American rock band At the Drive-In, released in 2001 as the third single from the album Relationship of Command.

The CD release in March 2001 came in a variety of international formats, including the standard two CDs in the United Kingdom.

[2] The song's lyrics and music video deal with the Juárez femicides, a series of rapes and murders in Ciudad Juárez, Mexico, of young women who worked in factories called maquiladoras.

Juárez is located just across the U.S.-Mexican border from El Paso, Texas, At the Drive-In's home town.

The song explicitly criticizes the federales, or the Mexican Federal Police, for their lack of response to these cases.
