This ruling is great news for the legions of muslim organizations in America that, to this day, run charity scams to funnel money to al-Qaeda and other terrorist organizations, foreign and domestic. Now, all they have to do is say, "I had no idea that Hamas and al-Qaeda were using my money to kill people. I thought they were using it to plant flowers and feed little kids." As long as they plead ignorance and don't keep any written records, they're free and clear to continue supporting terrorism.
