Joseph B. Frazier's El Salvador Could Be Like That is a memoir by a former Associated Press reporter who covered the country during the civil war. Its value lay in Frazier's descriptions of the people and how both everyday life and politics functioned "on the ground," with what I think is a balanced voice, pointing out inconsistencies or outright lies on both sides (though of course the lion's share of the violence was perpetrated by the right). Some of it gruesome, and all of it is sad. It was no easy job for reporters, who were attacked and, of course, lied to.
We gnawed through mountains of spin and did the best we could. There remained for a short time a 1950s-style naivete that told us if the U.S. government was telling us something, it must be true.
The facts on the ground quickly educated us otherwise (p. 14).
It is mostly chronological but tends to bounce around a bit (with funny additions like Surfer Bob, a guy from Florida who came to El Salvador for the surfing and then stayed). I noticed that Tim, who writes at Tim's El Salvador Blog, had recently reviewed it and thought the structure made it more important to have some background. I think that's true, but if you're interested in El Salvador and/or the era it's worth a look.
