Se la rompió

[Tyrn]

Hi,

En mayo de ese año hubo una breve huelga
cerca de Trapham Notch. Se la rompió en muy
poco tiempo gracias a esquiroles y a policías
municipales.

Is this "real" se, or is it le?

I suppose it's se. How much context do I have to analyze to tell one from another? Suppose I have just se la rompió. Is it enough?

I don't know about "real", but "se" is correct.

This "se" introduces an impersonal sentence; it doesn't have much to do with the direct or indirect object. The context is your first sentence. There isn't anyone to whom the action is related, so no "le" or "se" and "la" is the only substitution possible in the sentence.
Take a look here (http://forums.tomisimo.org/showthread.php?t=13735)for some other uses of "se". ;)
