Maybe a model worth copying would be the Law Enforcement Conduct Commission (LECC) of the Australian state of New South Wales – https://www.lecc.nsw.gov.au/ https://www.lecc.nsw.gov.au/ The NSW state government appoints the Chief Commissioner of the LECC – but by law, they must appoint a (serving or retired) senior judge. The other Commissioner is also appointed by the government, but the Chief Commissioner has a veto over the government's appointment of the Commissioner, and by law cannot be a serving or retired police officer – http://www8.austlii.edu.au/cgi-bin/viewdoc/au/legis/nsw/consol_act/lecca2016353/s18.html http://www8.austlii.edu.au/cgi-bin/viewdoc/au/legis/nsw/cons... It seems to be actually effective – at least sometimes – in going after police misbehaviour, for example: https://www.smh.com.au/national/nsw/are-you-going-to-attack-a-magistrate-next-strike-force-raptor-intimidated-solicitor-report-finds-20210326-p57eiz.html https://www.smh.com.au/national/nsw/are-you-going-to-attack-... Although in other cases maybe it has not done as good a job: https://www.abc.net.au/news/2022-02-20/nsw-police-watchdog-knew-about-fuller-racehorse-co-ownership/100843062 https://www.abc.net.au/news/2022-02-20/nsw-police-watchdog-k... And some view it as overly lenient: https://www.theguardian.com/australia-news/2022/apr/06/nsw-policeman-touched-aboriginal-boys-nipple-while-laughing-with-officers-watchdog-finds https://www.theguardian.com/australia-news/2022/apr/06/nsw-p... Still, I wonder what would have been the outcome in those kinds of cases if they had happened in the US?
