Unfortunately, California is one of those.
I have heard of one poor soul who has gotten over a dozen letters from the state demanding payment for internet purchases.
He has ignored them all, but if the recent past is any indication, I expect a tragedy sometime soon, when the state, in it's usual heavy-handed way tries to force collection.
But a few deaths should be OK. These people are now criminals.
He needs to order under the name Gray Davis. :)
