text: As you can probably see, principal, have phones at any time during the day can cause countless distractions and problems that would all have to be dealt with. Instead of dealing with all of that, you could just put a single simple policy into effect, dealing with every problem before hand.A camera that detects how you feel. Imagine walking on a peaceful day, you're trying to enjoy a nice spring day. On your walk you have random people trying to take pictures of you at the park. All you are trying to do is enjoy your day. Next thing you know, Goverment camera's using you as a study when you just want to be left alone. They dont even know you and you just want to enjoy the day. In the blink of an eye others have milions of photos of you. Its almost a invasion of privacy wouldn't you think?
