From a profile in the most recent issue of Rolling Stone:
Ailes begins each workday buffered by the elaborate private security detail that News Corp. pays to usher him from his $1.6 million home in New Jersey to his office in Manhattan. (His country home - in the aptly named village of Garrison - is phalanxed by empty homes that Ailes bought up to create a wider security perimeter.) Traveling with the Chairman is like a scene straight out of 24. A friend recalls hitching a ride with Ailes after a power lunch: "We come out of the building and there’s an SUV filled with big guys, who jump out of the car when they see him. A cordon is formed around us. We’re ushered into the SUV, and we drive the few blocks to Fox’s offices, where another set of guys come out of the building to receive ‘the package.’ The package is taken in, and I’m taken on to my destination.”
Ailes, like his outgoing colleague Glenn Beck, is very, very paranoid.
Ailes is certain that he’s a top target of Al Qaeda terrorists. “You know, they’re coming to get me,” he tells friends. “I’m fully prepared. I’ve taken care of it.” (Ailes, who was once arrested for carrying an illegal handgun in Central Park, now carries a licensed weapon.) Inside his blast-resistant office at Fox News headquarters, Ailes keeps a monitor on his desk that allows him to view any activity outside his closed door. Once, after observing a dark-skinned man in what Ailes perceived to be Muslim garb, he put Fox News on lockdown. “What the hell!” Ailes shouted. “This guy could be bombing me!” The suspected terrorist turned out to be a janitor. “Roger tore up the whole floor,” recalls a source close to Ailes. “He has a personal paranoia about people who are Muslim - which is consistent with the ideology of his network.”
Or maybe he's just afraid the Republican Party will want to get revenge on him for what he's done to them.
