The state can do anything it well wants. Laws have never been much of a blocker in the long run if the US had any ambition of stamping down mass murderers who just happens to have enough money to play games in the court rooms.

There are plenty of places where people have disappeared for less, including in the US. Now, I'm not advocating anything extrajudicial here, but let's not be naive and pretend like there's nothing that could be done.
