After 911 a woman in my city (Portland Oregon) called the police because she saw powder on the hood of her parked car - parked under trees that were shedding pollen. She though fer sher that evildoers were targeting her with anthrax spores or something. The police are required to respond to those calls with full bio-emergency gear, so it was a huge scene, road blocked off, police vans everywhere, people in full body protective gear taking samples of the "anthrax" from her car. The end result was a public announcement from the police asking the public to please use common sense before calling. The drama going on in people's heads sometimes ... yikes.
