(AP Photo/Susan Montoya Bryan) (Newser) – Want to keep the drug police off your property? Don't sow your land with birdseed. That's what a 74-year-old German farmer says he did—and the bird food contained hemp seeds, resulting in an accidental 10-foot-high cannabis crop, Der Spiegel reports. He explained that he wanted to grow sunflowers, police said. "But because he didn't have any sunflower seeds, he instead scattered half a sack of old bird seed he had at home." He swears he didn't know he was growing pot. As the police watched, the farmer plowed up the 3,000-square-foot field.
