Mak's legal defense was that he thought there was nothing improper about leaving the U.S. with a CD carrying his own published work[5][6][7] on U.S. defense technology,[3] despite his training from his employer indicating quite the opposite.[3][failed verification] He had intentionally released it without his employer's permission at a 2004 international engineering conference.[3][failed verification] He had been briefed every year on regulations regarding documents designated 'For Official Use Only' (FOUO)[8] and items restricted by export controls. His defense argued that making the data accessible to scrutiny by the general public negated its military value and made it acceptable to transport outside the United States, despite the fact that Chi Mak was the one who released the information, without authorization[citation needed]. The defense also argued that the data was in the public domain.[5][9][10]

The prosecution indicated that the data was nevertheless export-controlled and that it should not have been shared with foreign nationals without authorization.[3] The IEEE presentations cited by prosecution in the trial[11] are currently available on a worldwide basis, due to Chi Mak's unauthorized releases.[12][13]

Mak's brother and sister-in-law were apprehended by the FBI after boarding a flight to Hong Kong carrying one encrypted CD which contained defense-related documents.[4] They, along with their son as well as Mak's wife, all pleaded guilty to related charges. They served out their sentence and were deported to China.

On March 24, 2008, Chi Mak was sentenced to 24 years and 4 months in federal prison.[1]

Located a few doors down they had a sign which advertised Fried Chicken and Beer. As a huge fan of Bon Chon and Korean fried chicken in general I thought we should give it a shot.
