Guards stand watching prisoners stealing knives in the kitchen and do nothing about it. Have they been bribed to look the other way?

I see that a "Guard deployment mode + Patrol routes" feature is planned.
However what good is that if all they do is stand there or walk past some predetermined places?
I would like to be able to have a guard by my kitchen door but not only to watch prisoners come in and out but to do something about it.
Or at least if he is going to do nothing at least his presence should be enough to prevent prisoners from trying to get in. Not what happens now.
Too active guards might take away some of the players initiative but too passive ones are bad too.
