Would it be lazy of me to ask what year England took guns out of the citizens hands? Maybe there's a correlation between the simple circles and the timetable of the complexity of the formations. But the genius I am, I'd just say the aliens felt more compelled to the advancements this particular part of humanity has made by disarming themselves. Why not then make formations in China though? Are the chinese short on mathematicians? Or rice?
Yes chuck, why are you here? You don't seem interested in learning anything about crop circles, only maintain your stance that it's not possible for all the crop circles in England to be made by people because:
1. England is simultaneoulsy both pitch black and very lit up at night, allowing circlemakers to not see what they're doing, and for farmers to be able to keep watch over the full extent of their fields whilst walking the dog at two o'clock in the morning;
2. England is very small but at the same time quite big as it has remote dark corners where anything can happen;
3. On a small budget you could surveil all the fields in England and poke yer
gurrn in the face of those pot-smoking hoodlums dirtyin' up them fields.
By the way, if you want to discuss gun control, try Social Issues and Current Events. There's usually a thread running on that very subject down there. You might even meet some like minded souls.
We've never been big on gun ownership over here, so they've never been "taken out of our hands" so to speak. They were never really there in the first place. It's not in our constitution to own guns (yes, you are supposed to be able to read that two ways). In the UK you can own some types of firearm, if you have a licence, and as Zooterkin pointed out there is one group of people who more often than the general population will have a gun in the house.
Now, back to crop circles.
