Excuse the Daily Mail link sorry and the other link is a police murder with the mayor discussing police racism. The Dutch police are very good by nearly all accounts, but it's not hard to find accounts of racism.
The UK police have a very long and much worse history of racism with the Met being front and centre (less so now than 10+ years ago though). I won't post a link for them as it is extremely easy to find many many cases unfortunately. Pick you examples with them, beatings, killings, harassment, illegal searches etc. www.dailymail.co.uk/news/article-3163974/Boy-13-handcuffed-motorcycle-police-officer-run.html
Which is then called racist by its opponents.
