Japan Times : 'Crime manual' found in former yakuza office

The 206-page book, titled "Special Top Secret Information," covers more than 100 items on successfully committing crimes, they said.
...
The police said each item is preceded with the warning, "Do so at your own risk."

In a section on how to steal wallets and other belongings on the street, the book says, "Let's do purse-snatching amid the ongoing economic slump."

The book instructs readers to bend the license plates if they use motorbikes for crimes, and said easy targets on the street are housewives coming back from their shopping, according to the police.

The book also provides such information as how to borrow money from loan sharks without having to pay interest.
Sounds like petty criminal hand book for amateur yakuza, doesn't it ?
