I've been getting a lot of comments and questions these days about drones. As those remote-control flying machines drop in price, their numbers skyrocket, prompting concerns about safety and privacy. And I understand the worry. I mean, who wants a five-pound drone to drop on your head - or peek in your bedroom window?
Drones are everywhere these days, not without controversy, such as when one apparently was spying on a baseball team, and when one crashed into a hot spring at Yellowstone National Park.
But now, a drone is blamed for a riot during a soccer game in Europe.
Now you have to remember that folks in Europe take their soccer - or football as they call it - very seriously. But how can a little remote-control helicopter lead to mayhem on the field and in the stands?
