I think, even more so than an accident, the thought of random vandalism enacted on my property would bother me more than anything else. It's just so senseless. At least, with most accidents, it's just that. Assuming you, or the other car involved, weren't street racing or otherwise acting like an idiot, it's just an accident. The very nature of the word. However, with an act like that in the video below, it's intentional. It's malicious. And it pisses me off. I'm not quite sure what I would do if I caught someone doing this to my Porsche (or any of my property) but I'm fairly certain the results wouldn't be pretty. What about you, what would you do?
If you're wondering why the video above is from a Czech website it's because the owner of the Porsche in question was identified by some Redditors as Czech musician called Daniel Landa. The thread on Reddit goes on to say that Landa’s music has a Nationalist slant, that he’s a former Czech skinhead (apparently he's reformed in the last few years) and that the symbol you see on his car is that of Schutzstaffel or SS-Runen. If you see "SS" and you think Nazi, you're on the right track. My guess is this was completely a random act of senseless vandalism vs. a political statement. Either way, it's still wrong.
