I think someone did vandalize his property but did something a lot less "presentable" for the Mole to present to the Huffington Post. Technicality Tomlinson had to stage it a bit for media presentability - although it is true that someone vandalized his property. For example, the Huff Po can't publish an image of "Fat faggot nigger pig" scrawled on his bike, but they can publish something milk toast like "Gay virgin Fatrick." The video of the vandal was also probably really unconvincing so Pig had to put a penlight in his mouth and stand under the light.
Just my theory.
