there's no way in hell sites actively advertising the sale of buds would be run by cops. i thought you would know this being a pre-law student, but that is a textbook definition of entrapment. its the same principle as a cop running a spiked lemonade stand while his buddies have a dui checkpoint a couple hundred yards away. police cannot put citizens in positions to violate the law. they can moniter them but are legally not allowed to "solicit" crimes, for lack of a better term.
