Presumably the stall warnings were ignored because in "normal law" even if you try to stall the plane, a). the plane will not allow itself to stall and b). the stall warning will still sound. Hence the stall warning SHOULD NEVER SOUND in "normal law" mode. Therefore, the only time a pilot should hear the stall warning is when they actually have to intervene. Ultimately, if the plane was funcioning perfectly well and assuming the pilots weren't complete idiots, the problem was a 'usability' issue. (think again everytime you see a bug logged as 'usability' and assume it is not important!)
