I read many years ago that it was a tradition among writers - something of a rite of passage - to steal a copy of your own [first] book from a bookstore. Of course, back then, there weren't as many video cameras as there are now.
So... I divide the question into 2 parts:
a) Would you steal a copy of your first book if you were sure that you could get away with it? (i.e. Would the moral aspect not bother you?)
b) Given that you stand a higher chance of getting caught, would you dare to try it (in order to comply with this tradition / rite of passage)?
