Policemen and security guards wear hats with a peak that comes down low over their eyes. Apparently this is for psychological reasons. Eyebrows are very expressive and you appear a lot more authoritative if you keep them covered up. The advantage of this is that it makes a lot harder for cops to see anything more than six foot off the ground. Which is why painting rooftops and bridges is so easy.
BanksyI don't know if street art ever really works indoors. If you domesticate an animal, it goes from being wild and free to sterile, fat and sleepy. So maybe the art should stay outside.
