Like the definition of 'weapons of mass destruction,' the definitions of 'terrorism' and 'terrorist' are being challenged, extended and twisted in the Boston bombing case and others.

Over the weekend Libyans voted in the first free national elections since the demise of dictator Colonel Moammar Gaddafi. During all the changes and turmoil in Libya last year, there's one guest we interviewed a number of times on the show: Matthew VanDyke. Last year, VanDyke was captured by Gaddafi loyalists in Libya and held in solitary confinement for about six months before he escaped. VanDyke eventually came home, but he never lost his love for Libya or the Libyan people.

In August, The Takeaway first spoke with Matthew VanDyke and his mother Sharon. VanDyke, an American who described himself as a journalist, was captured by loyalists to Moammar Gadhafi in Brega, and held in solitary confinement for six months, before escaping on August 24. He finally escaped captivity in August, but has stayed on in Libya out of a sense of loyalty to the other men he was imprisoned with, joining the NTC fighters. Over the weekend, VanDyke returned home after eight months.

It sounds like the script of a movie, but the story of how American Matthew VanDyke ended up in the hands of the Gadhafi regime is very real. VanDyke traveled to Libya to help friends living there just as the war broke out between the rebels and the loyalists. He was captured in Brega, hit over the head and awoke in a prison cell. He was placed in solitary confinement twice, for 85 and then 76 days, before essentially escaping on August 24.
