It would be tough to pass by a chaotic scene like a woman stripping down to prove her innocence against a shoplifting accusation, but in the name of your traveling cash, it's best to keep walking. MSNBC reports that one of the many scams used to trap tourists involves an attractive young woman versus a street vendor, and once she's in her skivvies, all is forgiven and the crowd disperses. The woman gets to put her clothes back on, while tourists might find their wallets have disappeared during the commotion.
When you're traveling, avoid any scenes involving scuffles (and stripping). Unfortunately, pickpockets can be found anywhere and are often disguised in garb like business suits or dressed as tourists themselves. Assume the worst in suspicious situations and keep walking, as much as you might be curious about the outcome. Chances are, the ending will feature you minus one wallet.
