Who knows the back story on why this yahoo would smash these shop windows, but the end of the video makes it worth it all.

Some guy in Poland is caught on security video breaking a shop window with a rock, and then continuing to smash the rest of the windows.  A bystander approaches him, and they exchange words before he runs off and gets hit by a car!  HAHAHAHAHAHAHAHAHAHAHA, oh sorry...wait no I'm not, HAHAHAHAHAHAHA!

This is a must-watch, with Karma at its best!
