Just this last week. Apparently the fed's been watching him since 2009. Couldn't they follow something more important like curbstoners which is fairly common on CL?
They're bottom feeders who flip cars without a dealers' license or dealers who pretend to be individuals to evade restrictions that would apply to dealers. They sell cars dealers wouldn't be able to sell, like those with airbag deployed and taped over, non-working emissions, not road worthy, etc. It's a big issue on Craigslist.
And if they're concerned with the environment, they should be going after car owners who drive around with punched out cat, revoking business license from exhaust shops that install straight pipes, and such rather than doing a surveillance on someone that's selling R22...
But no, the gubbermint is more concerned that something about one guy's action is going to poop up the environment or something years later.
