God i hate fockers who cause vandalism, just go out there to intentionally destroy peoples belongings, for what reason? Who fkn knows. They all deserve slow but painful death, or that traditional Chinese tortures, nothing but scum.
If it's only a windscreen, you're pretty lucky.. There was a guy who posted in the Cosmetics & Styling section of this forum, the vandals stomped on the poor guys roof, resulting the roof to cave inside with few windows broken.
