answer:Suing the government sets a bad precedent for loons to go off on personal foreign policy crusades. Think of all the ridiculous domestic litigation stories we hear, and now imagine those jerks vying for even more money and attention. Equally important is the distraction. Private Saudi money has been vital to al Qaeda and ISIS, including money from the vast royal family. THAT is who should be held accountable. People trying to prove some government connection should be following that money trail instead.
