Bank Robbery Tactic

This video purports to be a bank robbery in Kiev. He first threatens a teller, who basically ignores him because she's behind bullet-proof glass.

Robot Safecracking

Robots can crack safes faster than humans -- and differently: So Seidle started looking for shortcuts. First he found that, like many safes, his SentrySafe had some tolerance for error.
