there are a lots of internet fraud from british, especially on craigslist. i personally experienced a fake check - never cash it anyway.
however, i am talking more than that. the guy i had experience with was hired as an accounting director by a good company - nevertheless, he was shameless cheater, munipulator, lied under the oath in the courtroom.
he fooled everybody - police officer, judge,.. watching how he did it is quite amusing!
he made up a story in the courtroom that he and his family have a conversation with me on an early sat afternoon. i had my friend (a white) witnessed that was impossible - I was with my friend's family for his birthday the whole afternoon, 30 minute drive way from where "the conversation took place"...
