Breakable Unbreakable Glass
To all the bank robbers reading this, please avert your eyes. We don’t want to be the people who feed you information that will encourage you to rob a bank. Okay, we think they’re gone. According to the OP, a lot of the “unbreakable” glass we see isn’t actually unbreakable. And the live CCTV feed? Yeah, they might not actually be recording.
Now, we can’t tell you whether any of this is true. The purpose is to keep people guessing, which is a deterrent in and of itself. If you’re feeling lucky, test out the system, but don’t say we didn’t warn you. Okay, bank robbers, come back. We’re moving on to the next item.
