Man steals a plane from Canada and lands it in the US

You would have heard of somebody stealing stuff from houses and running away undetected, or maybe even stealing a car and eventually getting caught. In some cases, you see those chases on TV where a criminal or a suspect is being chased by police, and either the criminal gets away, or police catches the person. But have you ever thought of a case where a person steals a huge plane, and then runs away ? There is no airborne police to catch such a person - so how do you catch such a person ? Well, in these times, when a plane is a security risk if in the wrong hands, you catch such a person through using fighter jets (link to article):

A pilot stole a plane in Canada on Monday afternoon and, with American jet fighters in pursuit, flew it all the way to Missouri before landing on a road, the authorities said. The single-engine, four-seat Cessna, stolen in Thunder Bay, Ontario, about 2:30 p.m., was intercepted by fighter jets over Wisconsin, where it prompted the evacuation of the State Capitol.
It kept flying south after the pilot failed to respond to radio calls and other signals. The pilot finally landed the plane on a road in Ellsinore, in southeastern Missouri, said Laura Brown, a spokeswoman for the Federal Aviation Administration.

How easy it to steal a plane ? This is not a cellphone or some other small item that can be easily stolen; this is a plane that caused the damage in the WTC attacks and when fully loaded with fuel, can cause large damage (even if a small plane).
