if any of these hacks were sincere and genuine they would be going after the government appraiser who valued the home at 800 and something thousand dollars if it was worth way way more than that right?
did jon stewart lie to the banks about the dimensions of the apartment he bought just to get a loan? no? well what about the person who bought the apartment - did they lie to the banks to get their money to buy the apartment? no? and will jon stewart not be paying his share of taxes on the $17.5 million dollars he rakes in off that sale? no? well then, have fun trying to invent a crime you can bring the guy to court over.
and who knows, maybe his apartment wasn't actually "worth" 17.5 million dollars, but somebody was willing to pay that much for it, in a world of capitalism, goods are only worth what somebody else is willing to pay for it. and it's not a crime to sell something for more than an appraiser says it is worth. as far as everything is concerned, jon stewarts apartment is worth 17.5 million dollars because that's what somebody else was willing to pay for it. it could have been worth 500 million dollars if somebody else agreed to pay that much for it.
