I think it's "the gods in long white houses". Tom said in a 1988 concert that he wrote the song a few days after the murder of three nuns in El Salvador in 1980.
I've put the chords to the song on my website here and I think I'd better put it here too:
A E
The army comes through, they curse us and prod us with guns.
B7 E
Sometimes they take us away - that's the end of that.
A E
They go where they like in our houses; their eyes miss nothing of value,
B7 E
And may the Virgin go with you if you've a gun or a knife.
A E
But who speaks for me? I, who have no voice.
B7 E
Who decides for me? For it seems I have no choice.
A E
Do I live, do I die, will my family survive?
B7 E
Will the ones who leap down from the trucks with their guns allow us our lives?
A E
One question I'd ask, if I dared, of the ones whom we never see:
B7 E
Guns and dollars are voices for you, but who speaks for me?
