Ways not to lock your bike

Under the bridge by Shoreditch tube station a couple of weeks back. I'd love to know whether the owner had the sense to know that if you're not going to lock your bike properly you might as well get to keep the rear wheel, or whether there is a really stupid rear wheel thief out there.

Clearly, to get that rear wheel he has had to rotate the bike by moving the lock along the stand from one end to the other, while twisting the bike around. You think while going through that convoluted move it would have occured to him to just take the front wheel off and have the rest of the bike.... like you say, some dumb fucks out there (including both parties involved here).
