From an interview of a man who breaks into safes, legally:
Q: It seems like you could use this knowledge in bad ways if you wanted to.
A: Clients often ask, jokingly, whether we learn our trade in prison.
Technically, the biggest difference between what a burglar does and what I do is that the burglar wants to get in and out quickly and doesn’t care if the safe ever gets used again. I take my time because my objective is opening it with minimal damage so the owner can use it again.
A criminal safecracker also needs different knowledge and skills, beyond the technical, that I don’t have or need. I don’t need to know how to avoid leaving evidence, circumvent an alarm system, plan a get-away, or fence-stolen goods.
