But this is precisely why Tech is the perfect place for people like this: we already don't trust anyone!

Consider Netflix's ChaosMonkey (or whatever their new simian name they have now). It messes with your IT infrastructure automatically to ensure that your software/system can handle these regular problems. Developers have to consider that hey, these things are going to happen all the time (rather than relying on luck that it doesn't happen) and they build super resilient systems. You ever even heard of a Netflix outage?

Now ask yourself this: How would you build your security infrastructure/system given the knowledge that literal convicted criminals would have access to some parts of the system? You'd become very inventive, creative, and build the world's best system. AAA (authentication, authorization, accounting) security? You'd find some new A's to add just to be sure.

If your system can't handle convicted criminals access it, how will it handle the ones who didn't get caught but now work for you?
