Here are a couple interesting and informative videos I saw a couple days ago. They're a bit long, but I find them interesting and entertaining. The relevance of these videos is that most scams are rather vague, and bringing criminal charges or a lawsuit is often not worth the time or money.
In summary Dave hears about a fire-sale from a guy with a warehouse full of helicopter parts, and incomplete helicopters. Initially, the deal is $150k for everything in the building. "Art" the seller, spends the day showing Dave a bunch of helicopters, parts, tools, full shelves, etc. Art acts cool and friendly and high-energy, telling stories, etc. But at the end says the price is $300k, not $150k. A lot of the stuff is a bit disorganized, and Dave needs someone with real expertise, and Art asks Dave for a $30k to $40k deposit. Dave negotiates that down to $10k, says "I trust him" and flys home, and agrees to meet again on Monday.
Dave's crew shows up again on Monday, but now the warehouse looks very different. Shelves are empty, boxes moved around. Alarm bells go off for good reason, but if Dave can still lock down a specific inventory for a specific price, it might still be a killer deal. Today, art is completely different. Very aggressive and accusatory. Attempts to make a very clear deal about what is included, are obstructed with excessively long winded stories, flip-flopping, irrelevancies, aggressiveness, distractions about "personal property," and accusations of being "military and strict." Art then also tries to claim this deal is him doing Dave a favor, that it's a "Donation," and that Dave is the one being up-tight.
Then things get even weirder, because Art wants the agreement to be $300k for nothing, but then Art donates all of it. Furthermore, the money is supposed to go to some offshore military contractor. Art also refuses to let Dave change the locks and secure inventory. Dave leaves when the situation goes from BAD (which you see on video) to apparently much worse, to the point Dave looks really freaked out.
My comments: I've seen enough scammers in action to recognize it was a a likely scam in the first video. In the 2nd video, it was a blatant scam. Art was okay with either keeping the $10k, or with sticking Dave with a deal so bad, he'd be an idiot to accept. Some people say Art was on drugs, etc, which was the reason for the behavior change. IMO, he was on drugs in the first video, and the behavior change was one of his many various scam tactics to discourage Dave from having a clean cut deal.
Was this a scam from a legal perspective? It would be hard to bring criminal charges, and a lawsuit probably would be a waste of time. But Art is clearly a well practiced scammer, and I've interreacted with other scammers exactly like Art. Almost none of Art's behavior was a mistake.
