USA Today reports that Steven Zahorksy of Bridgeport, Connecticut posted an ad on Craigslist–“Mary Jane in Fairfield County”–offering to sell half-ounces of “A Plus” marijuana for $220 and “B Plus” marijuana for $160. A Stamford police officer spotted the ad, arranged to meet Zahorsky at an I-95 rest stop, and there exchanged $320 cash for three-quarters of an ounce. (I guess there was a $10 discount for the extra quarter-ounce.) Police then arrested Zahorsky whose reported response was, in essence “Wha? Marijuana? Whaddya mean? I stopped for a burger.” In his wallet was $320, in his cellphone was the officer’s phone number, and in his apartment were more marijuana, hallucinogenic mushrooms, a digital scale (are triple-beam balances too old-school) and a shotgun.
