Believe me, most of us Americans want to see them arrested, but they haven't because apparently they technically haven't broken any major laws or some crap, I'm a little fuzzy on the details. Not to mention most of the family are lawyers, so I imagine they know more than few loopholes when it comes to legal disputes.
The best way to handle them is to just do what we stupid Americans do and just ignore them and wish some accident happens or their mouths drop off.
