Someone beat me to the mention of Hurricane Katrina, but I think that there's more to it than that.
O'Reilly is a fairly large man (6'4", 220 pounds). From what I've read about him, he enjoys his "intimidating" size. However, he was visibly shaken last year when he learned that there was supposedly a "viable" threat against him, which the FBI notified him of. Something to do with "terrorists" of the middle-eastern type.
Do you recall the celebrity/actor who had "viable" threats on his life, and the FBI issued a nation-wide CCW permit to that individual? That celebrity had been, in a way, an FBI "informant", but NEVER informed on any individuals....just their activities. Well, that celebrity was none other than the Screen Actors Guild President, Ronald Wilson Reagan! Reagan had passed on information about the COMMUNIST activities going on in the movie industry. Much of the information that Reagan passed on was found to be correct....and his fellow actors that were COMMIES started trying to find out who was "snitching" on them. Reagan was given a permit and carried a snub-nosed .32 revolver as a private citizen!
Perhaps O'Reilly, who is definitely a "celebrity" within the news media, has been afforded the SAME thing (?) I doubt if O'Reilly would stoop to hiring a bodyguard.
I'm not a big fan of O'Reilly, but from what I've seen and heard, he seems to be, uh, "fair and balanced". You may not LIKE his stance on guns, but he SEEMS to always be on the side of the honest, law-abiding, decent and God-fearing people. During the shows that he has done on the Virginia Tech massacre, he has pointed out the "looney-tune" aspect of the Korean shooter, and has attacked the "overlook" and ineptitude of the courts that allowed the "resident alien" to LEGALLY purchase his handguns. In my thinking, O'Reilly is addressing the CORRECT problem....not the GUNS, but the "evil" individual who was allowed to purchase them!
Hey, it's okay to be a "gun nut", but I hope that we all can agree that "nuts" should NOT have access to guns! That "Chop Suey Hui", or whatever his name was, had SEVERAL indicators that revealed that he was mentally unstable, including a police officer AND a judge that, in so many words, declared him a "danger to himself and others"! Besides that, I certainly don't think that a "permanent resident alien" status should give someone the same "freedoms" as an American citizen!
