Brett Kaffee is the last person on earth who should be a member of the paparazzi.

He's an ex-Marine who has traveled to every continent in the world, a former activist for organizations such as Witness for Peace, a scholar of political science who has had his photos used on the floor of the House of Representatives - and right now he is staking out Paris Hilton in the heart of cobble-stoned SoHo.

"You're not going to save the world through pictures," observes the 32-year-old New Jersey native, who describes his line of work as "90 percent James Bond and 10 percent photography."

"It's a waste of time."

And so he decided two years ago that he might as well make money off the world through pictures instead - by car, by scooter, by speedboat, by helicopter. He chases everyone from Sienna Miller ("she likes to bicker") to Madonna ("security is gonna kick your ass in") to Tom Cruise ("nearly impossible") to Hilton ("she performs her function exquisitely").
