Who are the 700 and why are they not on the Lists?

Here is the situation: a “religious” leader with a large following publicly calls for the assassination of a democratically elected leader of a sovereign country. I think you would agree that he should at least be considered a dangerous religious extremist and be sanctioned. The public advocacy of murder can also be considered a prosecutable offence. And if we go with the fashion of the time, he is a terrorist. Should this “religious” leader and his followers be put on some no-fly list, at least on flights going anywhere near the country of the proposed assassination? Following this logic, very much in line with the U.S., even Canadian, government, Pat Robertson and his followers should be on top of these list. Someone got to stop crazies taking a flight from Virginia Beach to Caracas and hijacking it to slam into the Presidential Palace!
