This is most industries in general. If you’ve ever worked retail and paid any attention you’ll notice there are more cameras on staff than customers. Shrinkage from shoplifters is expected and built into the system/budget. It’s harder to catch and prosecute and often enough too dangerous to stop in the moment. They also know staff is going to steal but internal thieves are often brazen and think they know how to cheat the system. Lots of places have fake camera domes to draw the attention of internal thieves to one area while having hidden cameras elsewhere.
