Well that is a shame if it is true... but it really sounds like a publicity stunt.
My local Republican building was vandalized I heard on the news. There were bb gun holes in the window. They said earlier this year someone smashed a window in. Another time someone sprayed on the wall "Bush lies people die." Well, that one was pretty funny, especially since it stayed up for awhile without any effort of removing it (It wasn't too big, but it stood out).
But it is a shame that people do this pointless stuff that doesn't do anything but encourage violence.
