For one thing, this game does not take place in America. It takes place in a small country just out of a dictatorship, where broad swaths of society (and especially the instruments of power, like the police and the government) are irredeemably corrupt and where organized crime basically runs the place. Before you say that couldn't happen, it happens ALL THE DAMNED TIME. Many countries are that way now. Hell, Russia was run lock, stock, and barrel by organized crime for almost a decade. So she can't go to the FBI because it doesn't exist there, and what law enforcement exists, exists to enforce the will of the criminals.
It's pretty plain that her husband is in on it, as is her best friend. How? Why? We don't know. But right now the only person in the whole game I trust to be on Laura's side is her dad. Everyone else is either actively working for the bad guys or hopelessly compromised by the bad guys.
