I don't think most of them would be that stupid. Just lazy. In a government official's mind, if the 50 page IT security document was filled out then he can't be held responsible when the shit hits the fan.
Being young and naive I, at first, thought it was just an isolated case of astonishing incompetence but I came to realize it was actually accepted as normal and good practice across many parts of government.
Once my idealism about civil service wore off I got out of there as fast as possible.
