If you don't know how a pint glass can be used as a weapon, then you haven't been drinking in some of the pubs near where I live. As an ex barman, I've seen what someone looks like with a smashed pint glass in their face, and I can tell you it's a lot worse than been hit with a hardback copy of the Da Vinci Code.
Its all a fuss about nothing until it happens to you.
