"War on terror" in El Salvador

From Tim's El Salvador Blog: last year El Salvador passed an anti-terrorism law, and now it has been applied to arrest the leader of street vendors in San Salvador for his role in protests that turned violent. This means he will lose many normal rights, with anonymous witnesses, harsher prison sentence, etc. There's nothing like vague laws in the name of the "war on terror" that can be applied to anyone at anytime for any reason.
