"Sell bhutane, cold medicine, and matches to the same customer, and an unknowing store clerk could well be arrested. These laws effectively deputized private business to begin policing the shopping habits of their customers – never a good idea."
Gracious! The last shopping trip to Wal-Mart I bought a two-pack of 1-bl propane canisters (to fuel my Coleman heaters), two 40-count boxes of Day-quill (to control my migraines), and a fireplace lighter (to light the Coleman heaters). I couldda' got myself arrested!
