Hamburg, Germany—Undercover pickpocket cop Michael-G is the first person we’ve met who exceeds our own nutcase-level of fascination with pickpocketry.

The day we spent together a year ago was all nuts-and-bolts info-sharing, technique-talking, statistic-rattling, drollness-swapping, photo-showing, video-viewing…. You know, the usual for pickpocket enthusiasts.

Over the years we’ve come to know a few others with extreme interest or knowledge in street thievery. The first may have been Terry Jones in Barcelona, whom we met exactly ten years ago. His observations of the pickpockets and bag snatchers in his own neighborhood led him to compile a loooong page of local street-theft incidents. On the surfeit of simple, opportunistic pickpockets, he’d already come to the conclusion that “there is little in the way of evolutionary pressure to make them improve their methods. The tourists are too many and too unaware, the police are too few, and the laws are too slack.”

The mysterious Monsieur F in Paris is a passionate pickpocket cop who works as “an invisible man;” his identity cannot even be hinted at. As one might expect of a Frenchman, the guarded Monsieur F shares his emotions freely. He tells us that, although his priority is arresting thieves and keeping the public safe, he “sometimes finds victims unfriendly and pickpockets compelling.” For example, when he “arrests a thief with AIDS who has just stolen a purse with ten euros, it is difficult judge the morality…”

We had the great pleasure of introducing Michael-G to Monsieur F, and then heard from both of their delight in their new friendship and information-exchange.

Last week we spent a relaxing day at Michael-G’s tidy, upscale home in a sleepy Hamburg suburb where, over cappuccinos (he’s a first-rate barrista, too), Michael-G’s obsession with all things pickpocket could not be concealed.

His library is extensive, possibly comprising every book and film on pickpockets in existence (including my own book). A life-sized mannequin stands nearby, fully-suited, seven bells sewn to its pockets. Michael-G uses the mannequin in his lectures, but I suspect there’s a little more to the relationship.

He’s taught himself to do a little stealing—for show, of course—so he can entertain and demonstrate at his police presentations. And he runs a website, http://www.taschendiebstahl.com.

Michael-G admits that he lives, breathes, and dreams pickpockets. Bob and I were most impressed by his pickpocket postcard collection. I didn’t even realize such things existed. They’re beautiful, mostly old, and from the world over.

Are there any pickpocket-obsessed painters or cartoonists out there?
