Bobby Kennedy was shot by a Muslim extremist?
I would have found Jay Lenno to be more likely.
But as for the others I guess you can say they were Muslim extremists, ecspecially #2. Who else would go out of their way to kidnapp and then hastly murder Israeli athletes, the KKK, Germans?
But if you want to get more technical, aside from numbers 1, 3, 5 and 8, they were commited by terrists working under the PLO. And for 9-12 were done by Al Qaeda or so the US government claims.
