lock fail or lock win?

from failblog

it's tempting to go along with the crowd and call this one a fail simply because it looks ridiculous.

on the other hand, the glass would probably break before the plastic crate does, and this bares a lot of similarity to the wooden beam that one often sees being used to secure large doors in historical depictions. as such one might be inclined to think it's actually a win because that's as secure as a glass door like that can get.

but did you consider that someone could slide something through the door and lift the crate off the handles?

this is an example that shows that thinking like an attacker takes practice, but it's important to evaluating how secure something is.
