One thing that is true from the story of the Fort Hood Killing and personal experience is that the government can be a nasty place to work. In the case of the Ft Hood incident the Killer was given a nasty performance appraisal and was under tight supervision. One would think that if management were so unhappy with this person and he wanted to resign they would say go for it, but it did not happen.
There is a perception that government workers are lazy. However, the truth is that they are often given impossible tasks and expected to be perfect according to inane numerical models that in many cases invent errors. An example being you did not check this box on a worksheet. The fact that the officer wrote the three items on the sheet that did the checked box was designed to record is just moot.
