Here's a fascinating story I missed during the Fourth of July week: NPR reports on an unlikely "respect" between criminal gangs in El Salvador and the nation's evangelical churches.

I really enjoyed the piece and felt like the writer did some excellent reporting.

After reading it all, though, I found myself wondering — and there's a chance this is just me being overly skeptical — whether the narrative is a bit too perfect. 

In other words, life is complicated, and the NPR storyline is simple. Perhaps too simple.

I'll explain what I mean in a moment. But first, let's set the scene with the opening paragraphs:

In El Salvador's capital, San Salvador, people drive around with their car windows closed to avoid petty theft. But when they enter neighborhoods controlled by gangs, they keep their car windows open, to show their faces. That way the gangs know they're not an enemy.

In the center of one such neighborhood, known as La Dina, a tiny Baptist church sits on a narrow street. In a neighborhood notorious for violence, it is the one place gangs leave alone.

The church underscores the growing ties between gangs in El Salvador and evangelical Christianity. In a country where Roman Catholicism has traditionally predominated, evangelicalism is growing and has gained the respect and endorsement of gangs — a rare point of agreement even for rival groups like Barrio 18 and MS-13, the country's two biggest gangs.

It has also left many boys and men growing up in gang-controlled areas with stark choices: According to academic research and interviews with pastors and former gang members, their only alternative to joining a gang — or getting out of one — is to become a devoted member of an evangelical church.

Later, NPR quotes an expert who has studied the relationship between the gangs and the churches — and he's certainly a strong source:
