Uh ... yeah ... so when you read down in the article, there are some items that give indication of why he bit a person and squeezed a person's arm. Because the were grabbing his head and a dude put a finger in his mount. Not execusing the other part, the dude should have rightly had his finger bit off at that point. In the end, its a bunch of brits and an person too drunk to fly. So scheiss em.
From the article w/the video:
One passenger, Stephen Mumford, attempted to restrain Libby by holding the Texan’s head.
One of his fingers slid into Libby’s mouth and the journalism student bit him.
Libby, a student at Texas Christian University, then squeezed the arm of Samantha Jackson, a BA air hostess, as she attempted to restrain him with Mr Mumford.
