“I Bent The Rules, I Got Away With It”

Imad Atallah has conducted an experiment:

For two consecutive days, I waited around the corner on the street where I usually park my car. […] On the third day […] I bought four legal parking stubs from the street meter, scanned them into my computer with Photoshop, then printed and used the counterfeit copies. Each copy was the exact replica of an authentic stub, the only difference being the expiration time. I then placed the counterfeit stubs on my car’s dashboard, replacing each with another after it had expired. As predicted, the meter man couldn’t tell the difference. I bent the rules, got away with it, and could have reaped the benefits for months had I relinquished my moral standards.

Why he did it? I have absolutely no clue, despite the fact that he wrote his stated reasons. In fact I read the article again and again and still couldn’t figure out what his stunt was meant to prove..
