Attacked by Thugs! is a great story of a hacker jumped (unsuccessfully) by some inept crooks in his native Poland, and then his subsequent adventures roaring around the city with a vanful of trigger-happy, all-caps-speaking police. Found by way of xach.
If you are ever, ever in Warsaw, I highly recommend you flag down a passing cop car and tell them you've been assaulted. You will meet with a kind of unconditional acceptance and emotional support that I didn't know could be found outside one's immediate family. The police will also go apeshit and run around with guns and screaming sirens in a way that very few families do, and for the police it's perfectly legal. I was lucky enough to flag down an entire van full of Warsaw's finest, and they immediately shouted for me to climb in and tell them which way to go. No invasive questions about who I was, no skepticism of any kind, not even questions about what had happened - just an instant desire to kick hooligan ass.
