To illustrate, this type of thing.

In the early 1970's I was employed as a "senior programmer/project 
manager" on a project at a rather large international merchant bank. One 
day I was hauled over the coals by the IT Director asking "Why doesn't 
your system stop the dealers from selling the stock lodged as security 
on a loan?". Thinking quickly I replied "Well, I guess the programmers 
assumed that no moron would even try that."

I doubt that would stand up in court these days.

But I do still remember the identity of the said programmer. (Wanders 
away with hands in pocket, whistling "Moonlight Shadow")
