This video demonstrates perfectly an important element to thievery. The idea behind this video is that if this guy is very obvious, people wont think hes trying to get away with anything. He makes it obvious that hes trying to cut a bike lose. People watching would think well if he was actually stealing that bike he wouldnt be so obvious.
Now apply this to other things. Imagine if you were in a store and someone next to you was folding up clothes in stacking them in their arms and walked right out of the store. you might not think he even stole them, or maybe he worked there. why would he have not tried to hide the fact that he stole them. he certainly didnt look suspicious. But if he was looking around every 2 seconds and kinda looked nervous stuffing merchandise under his shirt, he would look like a thief. Im not saying dont try to cover yourself, just keep in mind that a lot of times the best disguise is no disguise at all. I know that if I was going to steal something in front of a lot of people who might rat me out, I would pretend to not be stealing whatever it was. lol check it out
