In my job if I do something serious which endangers another person (albeit unintentional) I lose my job. I doubt colleagues would lie to protect me or themselves. in the NHS this is not often the case. Speaking from personal experience when something goes seriously wrong a web or lies is drawn. Ranks close and you are lied to. The culture has to change because not only is this immoral, it makes people on the receiving end of shoddy treatment all the more determined to see justice done. It would be better if a culture existed whereby a consultant, doctor etc... could say 'yes I made a terrible mistake and I am truly sorry'
