What happens if you take a sledge hammer to a weeping angel?
I know the Manhattan epsiode showed the crime boss had hit one to try and hurt it, but what if (out of self defense) you just plain pounded the thing with a sledge hammer? From the looks of the one the crime boss attacked, it CAN be damaged.
What if you dont' stop?
Could you pound one of those things into bits while they can't move?
And what happens to the bits if you then turn away?
Onscreen is canon, books are interesting. Movies change canon, scissors wrap paper...or...something.
