When I was a kid, (long before lasers were available in consumer goods), I had my door shoved in, and my wife and I forced to dress at gunpoint, because the loony downstairs had reported that we were "shooting a laser gun" at her. There were five or six officers there to arrest us, with guns drawn. Fortunately, the officer in charge was reasonable and listened to me when I told him that laser guns did not exist, if they had existed I wouldn't be shooting people with it, and that my neighbor was a loon, but it could have gone differently. The young cops at the time were completely caught up in the idea that there could be a laser gun. After a while we all laughed, but it was tense for a bit.
