bad cops, page-30

an organisations culture is much more then the hiring practices and in general HR can’t impact that as much as they’d like. You can’t turf out all the police that are shaping the culture and you can’t know everything going on. As far as I know the HR department does not making the hiring decisions even if they are involved they in the process

there has been plenty of work done to understand how the cultures are operating and many stations are closed systems and not helped at all by the fact they remain strictly hierarchical systems.

police training includes ethics. hiring practices include vetting to the best extent possible. However there is no perfect method of assessing integrity and ethics. In fact no hiring system in the world achieves better than around .5 to .6 validity. That leaves a lot of room for error in the best of systems

to blame the HR department seems a facile easy thing. You need to blame the line managers and the most senior officers first if you are talking ethical standards. But your statement remains extreme - every person is responsible for their own behaviour.
